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 Barometric pressure data were deleted from January 1 through July 16 because the probe was out of order. New probe was installed July 16 1100. The following are precipitation totals for each month there was rain: Calendar Day Daily Precipitation Totals (mm) Daily Rainfall Totals For: Jan 2002 19 .25 21 1.02 23 .25 26 8.89 28 11.68 30 .25 Monthly Total 22.35 Daily Rainfall Totals For: Feb 2002 3 .25 6 .25 7 6.10 16 6.86 17 22.10 18 1.02 19 3.05 20 1.27 21 .25 22 .25 Monthly Total 41.40 Daily Rainfall Totals For: Mar 2002 1 .25 6 7.87 7 10.16 10 4.06 12 .25 17 13.97 22 1.78 23 1.52 31 .25 Monthly Total 40.13 Daily Rainfall Totals For: Apr 2002 1 .25 10 .25 12 .25 13 .25 16 1.02 17 1.52 19 .25 22 .25 29 2.79 30 .25 Monthly Total 7.11 Daily Rainfall Totals For: May 2002 6 .25 9 .25 11 .25 16 .25 20 12.19 21 1.02 22 .25 Monthly Total 14.48 Daily Rainfall Totals For: Jun 2002 28 .25 Monthly Total .25 Daily Rainfall Totals For: Aug 2002 2 .51 3 .51 Monthly Total 1.02 Daily Rainfall Totals For: Sep 2002 3 .25 9 .25 24 .25 29 .25 Monthly Total 1.02 Daily Rainfall Totals For: Oct 2002 9 .25 12 .25 28 .25 Monthly Total .76 Daily Rainfall Totals For: Nov 2002 1 .25 6 .25 7 14.99 8 1.52 9 .76 10 .51 11 .51 12 .51 13 .25 14 .51 15 .76 16 .51 17 .25 18 11.43 25 .25 Monthly Total 33.27 Daily Rainfall Totals For: Dec 2002 2 .25 3 .25 4 .25 8 .25 9 7.11 10 .25 12 .25 13 38.86 14 12.70 15 3.56 16 16.76 17 5.33 18 1.78 19 19.81 20 8.89 21 4.06 22 .25 23 .25 26 .25 28 12.70 29 5.84 30 1.02 31 4.06 Monthly Total 144.78 CURRENTNESS REFERENCE: Observed 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 station is located at 36 deg 48'55.44"N, 121 deg 44' 16.8"W. The sensors are located on a 10 ft tower placed according to descriptions outlined in the MET SOP 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.

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. All data management performed by John Haskins. 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, Wind Speed 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 Temperature (°C), Time, Relative Humidity (%), Time, LiCor (PAR), Time, Barometric Pressure (mb), Time, Wind Speed (m/s), Time, Battery Voltage, Time (Array 244) c) Error/Anomalous Data Criteria Air Temp: - 15 min sample greater than max for the day - 15 min sample less than the min for the day - 15 min sample greater than 3.0 °C from the previous 15 minutes - Max and Min values not recorded for the day - 1-hour average greater than 10% above the greatest 15 min sample recorded in the hour Relative Humidity: - Changed by more than 25% from the previous 15 minutes - Max and Min values not recorded for the day - 1-hour average greater than 10% above the greatest 15 min sample recorded in the hour Rainfall: - Precipitation greater than 5 mm in 15 minutes - No precipitation for the month Wind Speed: - Wind speed greater than 30 m/s - Wind speed less than 0.5 m/s Wind Direction: - Wind direction greater than 360 degrees - Wind direction less than 0 degrees Pressure: - Pressure greater than 1040 mb or less than 980 mb - Pressure changes greater than 5 mb per hour - Max and Min values not recorded for the day - 1-hour average greater than 10% above the greatest 15 min sample recorded in the hour Time: - 15-minute interval not recorded For all data: - Duplicate interval data PROCESS DATE: 20060222
