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 Estuary in
order to observe any environmental changes or trends over time. The data is also used for
specific research studies relating to migrating shorebirds, horseshoe crab spawning, atmospheric
deposition of nutrients and pesticides.
SUPPLEMENTAL INFORMATION:
Associated researchers and projects The NERR Water Quality Monitoring Project also has three 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 three sites represent a pristine site and the other two to represent impacted
sites. Measurements are taken every 30 minutes over roughly two-week collecting periods. 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. Three samplers are positioned across the St. Jones watershed and one is in the
Blackbird watershed. Other remarks/notes 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. LiCor: Prior to the installation of the new NERR_4.CSI program, 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 are changed in the raw data,
we cannot confirm that they are all valid data points. Relative Humidity: Prior to the
installation of the new NERR_4.CSI program, all values over 100% were altered in the raw data to
read 100%. These values may indicate super saturated air, calibration problems, or a sensor
malfunction. Because these values are changed in the raw data, we cannot confirm that they are
all valid data points. January Rainamount (mm) 5 .254 6 .254 8 6.096 14 2.286 15 1.016 16 .762

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 Scotten Landing.

NACOMPLETENESS REPORT: Data collection period The meteorological monitoring program was started
in October 1997 at the DNERR and has been continuos through the present. The data collection
format has followed NERRS protocol since standardized meteorological program development in
November of 1998. Deleted Data Missing Data The following data are missing (-99999) due to
replacement work on temperature sensor: ArrayID CalD JulianD Time Error Message 150 19 353 1030

LINEAGE/PROCESS STEP: PROCESS DESCRIPTION: Additional Description: Entry verification 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 (nerr303.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 CDMO Weather Data
Management Program (WDMP) was used to convert the files to an Access database. This program was
developed in Visual Basic to interface with the NERRS data collection schedule (see 2b of the
Entry Verification section for the data collection schedule). The WDMP will automatically input
and convert the monthly raw data file into and Access Database. There are three main steps the
WDMP performs. First, it converts the comma delimited monthly raw data file into an Access
Database. Secondly, it checks the data against a predetermined set of error criteria (see Part C
of this section). Finally, it produces error and summary reports. Any anomalous data were
investigated and are noted below in Anomalous Data section. Any data corrections that were
performed are noted in the Data Correction section below. Common errors noted in the monthly
error reports were wind speeds below the 0.5 m/s criteria, temperature change of greater than 3
C in a 15 minute period, and precipitation difference of greater than 5mm in 15 minutes. All
errors of these types were double checked with other data that could support such "anomalous"
weather changes and noted in the sections that follow. Wind speeds below the 0.5 m/s criteria
are common between 1900 and 0600 hours and are not individually checked. Both raw data files and
Access databases were saved to the DCP server with daily tape back-up. Both Robert Scarborough
and Mike Mensinger conducted data management and QA/QC activities. 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. b) Data Collection Schedule i) Data is collected in the following
formats. (1) Sample data points are collected every 15 minutes. (2) Hourly averages are
collected every 60 minutes. (3) Every 24 hours daily averages, maximums with time, and minimums
