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:
Research objectives (Campbell Weather Station): The principal objective is to record long-term meteorological data to track changes in meteorological conditions that can be associated to changes in estuarine habitats and conditions. At the same time, the collected information will provide reliable baseline information to be used by federal and local agencies, universities, researchers, educators ... and local communities in decision-making processes and the development of valuable monitoring and Research activities.
SUPPLEMENTAL INFORMATION: Associated researchers and projects Jobos Bay NERR system-wide water quality monitoring program has four YSI continuous sampling stations (s9,s10,s19,s20) that collect long term data, every 30 minutes, of different parameters to track changes in water quality in the Bay. Parameters include temperature, dissolve oxygen (% saturation, mg/L), specific conductivity, salinity, depth, pH and turbidity. Station 9 was originally selected as an example of an impacted site and station 10 as the reference site. Station 19 was deployed over seagrass beds, Thallasia testudinum, in the bay and station 20 was deployed over sea grass bed communities near Cayos Caribe reefs. Other remarks/notes Please note that for the south part of the island of Puerto Rico, the wind is blowing in from 60º to 240º most of the time. It is very rare to see wind blowing in NorthSout and WestEast directions.

SPATIAL DATA ORGANIZATION INFORMATION : Indirect Spatial Reference: Site location and character The Jobos Bay National Estuarine Research Reserve (JOBNERR) is located on the southern coastal plain of the island of Puerto Rico, the reserve is within the West Indies geographical area. JOBNERR is composed of two major areas: (1) Mar Negro, located on the western margin of the Bay, and (2) Cayos Caribe, a chain of 15 tear-shaped islets located to the southeast. The Mar Negro area comprises the bulk of the Reserve, and consists of mangrove forests and a complex system of lagoons and channels interspersed with salt and mud flats. Coral reefs and seagrass beds, with small beach deposits and upland areas fringe Cayos Caribe mangrove islands. The weather station is located in front of the Visitor Center in the community of Aguirre. The Wind Sentry, Temperature and Humidity sensor, Barometric Sensor and LiCor Sensor are all located on a 10m aluminum tower following the descriptions outlined in the CDMO Manual Version 4.0. The Tipping Bucket Rain gauge is located to the SW side of the tower. The sensors were wired to the CR10X following the protocol in the CDMO Manual. A description of the specific sampling station follows: The weather station is located in front of JOBNERR Visitor's Center. (latitude 17 57' 23.498"; longitude. 66 14' 18.690").

The CDMO Data Logger Program (nerr30.csi) was loaded into the CR10X datalogger that 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 was uploaded through a storage module, at the beginning of every month, via a direct connection to a computer located in Jobos Bay Laboratory. The data was saved as a monthly raw data file (RAWjan01.dat) onto a separate hard drive and backed up onto Zip disk and CD. 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 NERR Meteorological Data Collection Schedule (see 2b of the Entry Verification section for the data collection schedule). The WDMP automatically imports and converts the monthly raw data file into an 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 Appendix G for the CDMO Meteorological Data Collection Error/Anomalous Data Criteria). Finally, it produces error and summary reports. Any anomalous data was investigated and noted below in the Anomalous Data Section. All data corrections performed are noted in the Data Correction Section below. Common errors noted in the monthly error reports include wind speeds below the 0.5 m/s criteria, temperature change greater than 3 C in a 15minute period, and precipitation difference greater than 5mm in 15 minutes. All errors of this type were double checked with other data that could support such "anomalous" weather changes and noted in the sections that follow. No anomalous data was corrected for 2001 data. Data corrections were performed on some 24 hour maximum and minimum values due to problems further described in the section. Both raw data files and Access databases were saved on Compact Disc. 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
