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
Purpose:
The principal objective is to record long-term meteorological data within the York River watershed in order to observe any environmental changes or trends over time. Samples were taken every 5 seconds and 15 minutes over roughly one- week collecting intervals. SUPPLEMENTAL INFORMATION: Associated researchers and ... projects Taskinas Creek watershed is a site of limited
impact due to development or recreational use. There is a water quality station and a stream
gauge station at this site. This site is being developed as a control site for watershed work in
the area. Other remarks/notes Rain Events: January 2002 Date RainAmount (mm) 4 .508 6 28.448 7

SPATIAL DATA ORGANIZATION INFORMATION:
Indirect Spatial Reference: Site location and character Taskinas Creek (TC) Component: The Chesapeake Bay NERRS of Virginia maintains a
long-term water quality- monitoring program, and stream gauge station at Taskinas creek station.
The Taskinas Creek station is located in the transitional zone of the York River tributary in
the York River State Park. The Chesapeake Bay National Estuarine Research Reserve in Virginia is
located on the York River, a tributary of the Chesapeake Bay. The weather station is located at
York River State Park that borders the York River and includes the Taskinas Creek tributary. The
bordering river is 50 km long, 38 kilometers from the mouth of the river, and it 2.25 kilometer
wide near the weather station, and. The weather station in located (37°24' 50.79850" N, 76°42'
44.51934" W) on a bluff (11m elevation) 60m from the York River in a manicured lawn area of the
park. No trees or other major structures within a 35m radius of weather station. The stream
gauge located 2km NW (288 degree of weather station and the water quality station located 200m
(298 degree) of weather station. The weather station has a landscape fence around it to keep
visitors of the park away from the weather station. All the instruments, the Wind Sentry,
Temperature and Humidity sensor, Barometric Sensor, and LiCor Sensor all located on the
approximately 3.5 m aluminum tower following the descriptions outlined in the Campbell
Scientific CR10X Based Meteorological Monitoring Station Standard Operating Procedure. The
Tipping Bucket Rain gauge is located within 2m of the tower. The sensors were wired to the CR10X
following the protocol in the CDMO Manual.

STEP: PROCESS DESCRIPTION: Additional Description: Entry verification a) Data Input Procedures:
The 15-minute, 1-hour average, and 24-hour data were downloaded from each instrument on the
weather station to a Campbell Scientific CR10X datalogger. The CDMO Data Logger Program
(nerr.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 laptop computer to which the data was downloaded manually in the field. Data was downloaded
monthly from a storage module located within the weather station. 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. Eric Wooden performed all data management. Gemteck's EQwin version 5 and the CDMO
developed Microsoft Excel EQWinFormat.xls macro now replaces the WDMP as the NERR MET database
management program and primary QA/QC program. 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. For data collection, the CR10X datalogger was programmed to collect data in the
following formats: i) 15-minute data are collected instantaneously for Air Temperature (C),
Relative Humidity (%), Barometric Pressure (mb), Wind Speed (m/s), and Wind Direction (degrees).
15-minute Precipitation (mm) and PAR (mmol/m^2) data are totaled from 5-second readings, prior
to NERR_4.CSI ii) 15-minute average, maximum and minimum data are averages of 5-second readings
for Air Temperature (oC), Relative Humidity (%), Barometric Pressure (mb) and Wind Speed (m/s)
with NERR_4.CSI. iii) Hourly average, maximum, and minimum data are averages of 5-second
readings for Air Temperature (oC), Relative Humidity (%), Barometric Pressure (mb), Wind Speed
(m/s), and Wind Direction (degrees). Hourly totals for PAR (mmol/m^2) and Precipitation (mm) are
totals of 15-minute readings. iv) Daily average, maximum and minumum data are averages of
5-second readings for Air Temperature (oC), Relative Humidity (%), Barometric Pressure (mb),
Wind Speed (m/s), and Wind Direction (degrees). Daily totals for PAR (mmol/m^2) and
Precipitation (mm) are totals of 15-minute readings. Data were stored on a Campbell Scientific
storage module (SM192 or SM4M), which was retrieved monthly. The data were downloaded and
pre-processed as described in Section 2. QA/QC of the data was conducted using either the WDMP
or EQWin. WDMP error reports and EQWin queries were based on the following anomalous data
criteria: Air Temp: - 15 min sample not greater than max for the day - 15 min sample not less
than the min for the day - 15 min sample not greater than 3.0 C from the previous 15 minutes
(WDMP only) - Max and min temp recorded for the day (WDMP only) - 1-hour average not greater
than 10% above the greatest 15 min sample recorded in the hour (WDMP only) -Sample not greater
than 50 C or less than 30 C (EQWin only) Relative Humidity: -Not changed by more than
25% from the previous 15 minutes (WDMP only) -Max and min humidity recorded for the day (WDMP
only) -1-hour average not greater than 10% above the greatest 15 min sample recorded in the hour
(WDMP only) -Sample not greater than 100% or less than 0% (EQWin only) Pressure: - Pressure not
greater than 1040 mb or less than 980 mb (WDMP only) - Pressure changes greater than 5 mb per
hour (WDMP only) - Maximum and minimum values recorded for the day (WDMP only) -1-hour average
not greater than 10% above the greatest 15 min sample recorded in the hour (WDMP only) -Sample
not greater than 1060 mb or less than 900 mb (EQWin only) Wind Speed: - Wind speed not greater
than 65 m/s or less than 0.5 m/s (WDMP only) -Wind speed not greater than 30 m/s (EQWin only)
-Wind speed not less than 0.5 m/s for 12 consecutive hours (EQWin only) Wind Direction: - Wind
direction not greater than 360 degrees or less than 0 degrees Rainfall: - Precipitation not
greater than 5 mm in 15 min - No precipitation for the month (WDMP only) Photosynthetically
Active Radiation (PAR): -Sample not greater than 5000 mmol/m^2 or less than 0.5
mmol/m^2 Time: - 15-minute interval recorded For all data: - No duplicate data PROCESS DATE:
