Summary
Abstract:
Meteorological monitoring is conducted at 26 National Estuarine Research Reserves (NERR) from at least one location within or adjacent to the reserve. Data are collected every 5 seconds and averages are produced from this data at quarterly (15 minutes), hourly (60 minutes) and daily (1440 minutes) intervals. The parameters collected within these ... intervals are: averages,
maximums and minimums of air temperature, relative humidity, barometric pressure, wind speed,
wind direction, precipitation and photosynthetically active solar radiation. Research
objectives: The principal objective is to record long-term meteorological data for the St. Jones
component of the Delaware National Estuarine Research Reserve in order to observe any
environmental changes or trends over time. The data are also used for specific research studies
relating to atmospheric deposition of nutrients and pesticides, and nutrient runoff influences
from encroaching urbanization on estuarine systems. The meteorological data also serves a
supporting role for the SWMP water quality and nutrient data sets since meteorological
conditions directly impact these projects.
SUPPLEMENTAL INFORMATION:
Associated researchers and projects. The NERR Water Quality Monitoring Project has four stations located at the DNERR. The
principal objective of this study is to record long-term water quality data for St. Jones and
Blackbird watersheds in order to observe any physical changes or trends in water quality over
time. The Blackbird station represents a pristine site while the the three St. Jones River
stations represent impacted sites. Measurements are taken every 30 minutes over roughly two-week
collecting periods. The NERR Nutrient Monitoring Project has five stations located at the DNERR.
The objective of this monitoring program is to provide baseline information on inorganic
nutrient and Chla water quality status in the Delaware NERR while also contributing to baseline
information nationally. Diel and grab samples are collected monthly at each of the five sites.
In addition atmospheric deposition of rainfall events is performed in the DNERR watersheds to
monitor and characterize the nutrient input to the estuary from differing storm events and
seasonally. One sampler is currently positioned in the St. Jones watershed (the additional two
were decomissioned in 2003) and one is located in the Blackbird watershed. Other remarks/notes
a) LiCor: Prior to the installation of the new NERR_4.CSI program on 11/14/2003, all values less
than 0 were altered in the raw data to read 0. These values may indicate an incorrect
multiplier, calibration problems, or a sensor malfunction. Because these values arechanged in
the raw data, we cannot confirm that they are all valid points. b) Relative Humidity: Prior to
the installation of the new NERR_4.CSI program on 11/14/2003, all values over 100% were altered
in the raw data to read 100%. These values may indicate an supersaturated air, calibration
problems, or a sensor malfunction. Because these values are changed in the raw data, we cannot
confirm that they are all valid points.

SPATIAL DATA ORGANIZATION INFORMATION:
Indirect Spatial Reference: Site location and character The Delaware National
Estuarine Research Reserve is comprised of two component sites, the St. Jones River and
Blackbird Creek components. Both components are located along the Delaware Bay Coast. The St.
Jones River Component is located in central Kent County Delaware, east of the State capitol
city, Dover. The Blackbird Creek component is located in the unincorporated area of Southern New
Castle County. The meteorological station site, is located in the St. Jones DNERR component. It
is located in a tidal marsh area with a wooded fringe area 100 m to the north, 75 m to east, 75
m to the west and 1+ km to south. The wooded area is of an approximate average height of 16 m.
Position: Latitude 39 degree 05' 20.05" N Longitude 75 degree 26' 12.78" W The unit is mounted
on a 3-meter tower adjacent to the boardwalk that crosses the marsh. The elevations above the
marsh surface are as follows; Barometric pressure - 2.2 m, temperature and relative humidity -
2.9 m , wind and PAR - 4.5 m, highest point on tower (lightning rod) - 4.9 m. The rain gauge is
2.4 m above the surface and 3 m south of the tower. The adjacent boardwalk is 1.1 m above the
surface with a railing height of 1.0 m. A vegetative cover of spartina surrounds the area with
an average height of 1 m. The tower and rain gauge are both 1 m east of the boardwalk. The
weatherstation is located approximately 2 km from the water quality datasonde at Scotton
Landing, approximately 4km from the water quality station at Lebanon Landing, and approximately
10km away from the water quality monitoring station at Division Street.

2004 (none) LOGICAL CONSISTENCY REPORT: NACOMPLETENESS REPORT: Data collection period The
meteorological monitoring program was started in October 1997 at the DNERR and has been
continuous through the present. The data collection format has followed NERRS protocol since
standardized meteorological program development in November of 1998.The 2004 data set runs from
January 1, 2004 (Julian Date: 1)(00:15 EST) through December 31, 2004. Deleted Data a) 15-60
minute minimum barometric pressure and time readings were removed from October 21,
2004 1800 EST due to unrealistically low values of 600 mb. b) 24-hour (144) minimum barometric
pressure data for October 21, 2004 were removed. Anomalous data was collected during this day
that affected the daily value. b) All 24 hour (144) data for November 30, 2004 were removed as a
result of missing data earlier in the day. c) 15, 60 minute temperature data (avr, min,
max) from December 21, 2004 1400 EST were removed. Unrealistic values were recorded by the
sensor during a sensor change. d) 24-hour (144) temperature data (avr, min, max) for December
21, 2004 were removed. Anomalous data was collected during this that affected the daily value
for each of the three daily temperature values. e) 15 and 60 minute relative humidity data (avr,
min/time, max/time) from December 21, 2004 1400 EST to December 22, 2004 0900 EST were removed.
Anomalous data were collected during this time due to a wiring error that took place during
sensor recalibration on December 21, 2004. f) 24-hour (144) relative humidity data (avr,
min/ime, max/time) for December 21-22, 2004 were removed. Anomalous data was collected
during this time due to a wiring error that took place during sensor recalibration on December
21, 2004. g) 15 and 60 minute barometric pressure data (avr, min/time, max/time) from December
21, 2004 1400 EST to December 22, 2004 0900 EST were removed. Anomalous data were collected
during this time due to a wiring error that took place during sensor change on December 21,
2004. h) 24-hour (144) barometric pressure data (avr, min/time, max/time) for December 21
-22, 2004 were removed. Anomalous data was collected during this time due to a wiring
error that took place during sensor recalibration on December 21, 2004. i) PAR data (15-60 minute) from December 21, 2004 1430 EST to December 28, 2004 0900 EST were removed.
The new Licor calibration number was not altered in the program at the time of sensor change on
December 21, 2004. The error was identified on December 28, 2004. j) 24-hour (144) PAR data were
removed from December 21, 2004 to December 28, 2004. The new Licor calibration number was not
altered in the program at the time of sensor change on December 21, 2004. The error was
identified on December 28, 2004. k) 24-hour (144) data from December 28, 2004 were deleted for
the following parameters: temperature (avr, min temp, min time), Relative Humidity (avr,
max/min, time), barometric pressure (avr, max/time), wind direction, wind speed (avr, max/time),
PAR and avr battery voltage. Max temp/time, pressure min/time and wind speed min/time were not
removed as it is clear these could only have taken place after the program upload based on the
data trends. Missing Data Data are missing due to equipment or associated specific probes not
being deployed, equipment failure, time of maintenance or calibration of equipment, or
repair/replacement of a sampling station platform. For more details on deleted, see the Deleted
Data Section (12). If additional information on missing data is needed, contact the Research
Coordinator at the reserve submitting the data. November 2004 a) All data are missing from
November 04, 2004 (0715 EST) through November 12, 2004 (0730 EST) due to a CR10X shutdown
associated with storm activity. b) All data are missing from November 22, 2004 (2245 EST)
through November 30, 2004 (1200 EST) due to a CR10X shutdown associated with storm activity.
LINEAGE/PROCESS STEP: PROCESS DESCRIPTION: Additional Description: Entry verification The
Centralized Data Management Office converted all SWMP weather data collected with CR10X program
versions prior to version 4.0 which was distributed in October 2003. This was necessary in order
to merge the old data format (12 array output) with the new data format found in version 4.0 (3
array output). The new format produces averages, maximums and minimums every fifteen minutes
(array 15), every hour (array 60) and every day (array 144) for any sensors hooked up to the
CR10X. Specifically, the 150 and 151 fifteen minute data were converted to the new 15 array; the
hourly 101, 102, 105 and 106 data were converted to the new 60 array; and the daily 241, 242,
243, 244, 245 and 246 data were converted to the new 144 array. With the new format, the use of
55555's to code for deleted data and 11111's to code for missing data has been abandoned. Hence,
all 55555's or 11111's contained in the SWMP weather data collected prior to Version 4.0 of the
CR10X program were removed and left blank. a) Data Input Procedures: The 15-minute, 1-hour
average, and 24-hour meteorological data were downloaded from each instrument on the weather
station to a Campbell Scientific CR10X datalogger. The CDMO Data Logger Program (NERR4.csi) was
loaded into the CR10X and controls the sensors and data collection schedule (see 2b of the Entry
Verification section for the data collection schedule). The CR10X then interfaced with the
PC208W software supplied by Campbell Scientific. This software was located on a computer to
which the data was uploaded (every 15 minutes) via a short haul modem to a computer located at
St. Jones Center for Estuarine Studies. The data was saved as a raw data file (SJ_RAW.dat) onto
a separate hard drive and backed up onto Delaware Coastal Programs' (DCP) server. Once an entire
month of data was available, the raw (.dat) file was imported into Excel and run through the
EQWin format macro that was designed by the CDMO to reformat the header columns, insert station
codes, insert a date column (mm/dd/yyyy), correct the time column format, and reformat the data
to the appropriate number of decimal places. After this initial pre-processing takes place the
data is copied from Excel and imported into EQWin using the weather.eqi import file. Finally,
data were compared against a predetermined set of error criteria (see Part C of this section)
using a series of EQWin queries. Monthly and yearly EQWin graphs were also investigated as part
of the QA/QC process. EQWin was also used to generate statistics, view graphs, create customized
queries and reports of the data, cross query the water, weather, and nutrient data, and
finally export the data to the CDMO. Any anomalous data were investigated and were noted below
in the Anomalous Data section. Any data corrections that were performed are noted in the Deleted
Data section below. Missing data, data that was never collected, is documented in the Missing
Data section. Common occurrences noted in the monthly queries were humidity values exceeding
100% and small negative PAR values. These two occurrences are not addressed directly in the
anomalous data sensor since they are within the range of the two sensors. All errors were double
checked with other data that could support such "anomalous" weather changes and noted in the
sections that follow with. Wind speeds below the 0.5 m/s criteria are common between 1900 and
0600 hours and are not individually checked. All raw and edited data files were saved to the DCP
server with daily tape back-up. Raw data files were also sent via FTP to the CDMO server for
additional back-up. Michael G. Mensinger conducted all data collection, data management, and
QA/QC activities. b) Data Collection Schedule i) Data is collected in the following formats. (1)
