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 principle objective is to record long-term meteorological data for Elkhorn Slough to observe
any environmental changes or trends over time. These data are also collected as a part of a
county wide monitoring program and are made available for researchers that may be interested in
them.
SUPPLEMENTAL INFORMATION:
Associated researchers and projects. Rain data from the weather
station are shared with the Naval Post Graduate School who in turn organize these data from many
stations in the county. These weather data are also combined with water quality data for
analysis and correlations with rain events. Other remarks/notes Rain Events: January Date Rain

SPATIAL DATA ORGANIZATION INFORMATION:
Indirect Spatial Reference: Site location and character The Elkhorn Slough NERR is located on
the central California coast at the head of the Monterey Bay. There is one weather station on
the reserve that is located approximately one kilometer south of the South Marsh water quality
site. The coordinates for this station are 38° 48' 55.44" N, 121° 44' 16.8" W. The sensors are
located on a 10 ft tower placed according to descriptions outlined in the CDMO Manual V 4.0 and
are located approximately 200 feet above the marsh on a bluff in the uplands of the marsh. The
tipping bucket is located to the west away from the tower. There are no shadow or wind
obstructions from buildings or trees in the immediate area surrounding the location of the
sensors.

LINEAGE/PROCESS STEP: PROCESS DESCRIPTION: Additional Description: Entry verification The CDMO
Weather Data Management Program was used to QA/QC the data, verified by John Haskins. 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. Data are saved in the
Campbell Scientific format on both computer and backed up onto compact disc. A common error that
is encountered is wind speeds below 0.5 m/s. The storage module is manually brought into the lab
and downloaded. Two storage modules are used so no data is lost while downloading data from the
module. 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. 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) 15 minute data are
instantaneous readings except for PAR and precipitation data that are totalized from 5-second
samples sorted by date and time. (Arrays 150 and 151) 2) Hourly averages (Arrays 101 and 102)
are calculated from 5 second samples sorted by date and time except for PAR and precipitation
data that are hourly totals calculated from 15 minute totals (Arrays 105 and 106). 3) Daily
average (arrays 241 and 242), maximum with time, and minimum with time (arrays 243 and 244) are
calculated from 5 second samples sorted by date and time except for PAR and precipitation data
which are 24 hour totals calculated from hourly totals (arrays 245 and 246). ii) 15 minute
sample point parameters: Date, Time, Air Temperature (°C), Relative Humidity (%), LiCor (PAR),
Barometric Pressure (mb), Wind Speed (m/s), Wind Direction (Array 150); Rainfall (mm) (Array
151) iii) Hourly average parameters: Date, Time, Air Temperature (°C), Relative Humidity (%),
Barometric Pressure (mb) (Array 101); Wind Speed (m/s), Wind Direction, WindSpeed Maximum (Array
102) iv) Hourly total parameters: LiCor (PAR) (Array 105); Rainfall (mm) (Array 106) v) Daily
Average parameters: Date, Time, Air Temperature (°C), Relative Humidity (%), Barometric
Pressure (mb) (Array 241); Wind Speed (m/s), Wind Direction, Wind Direction Standard Deviation
(using Yamartino's Algorithm) (Array 242) vi) Daily Total parameter: LiCor (PAR) (Array 245);
Rainfall (mm) (Array 246) vii) Daily Maximum parameters: Date, Time, Air Temperature (°C),
Time, Relative Humidity (%), Time, LiCor (PAR), Time, Barometric Pressure (mb), Time, Wind Speed
(m/s), Time, Battery Voltage, Time (Array 243) viii) Daily Minimum parameters: Date, Time, Air
