Sevilleta LTER Meteorology Data, 1991

This file contains the weather data for a network of 8 permanent weather stations on the Sevilleta Wildlife area, Langmuir Labs, and Bosque Del Apache Wildlife area for the year 1991. Station 40 has been in operation since the middle of 1987; Stations 41-44 were installed in the early part of 1989; Station 45 was put into operation on 26 Jan 1990 (hour 15); Station 46 was put into operation on 31 Aug 1990 (hour 17); and Station 47 was put into operation on 08 Jan 1991 (hour 16). The geographic locations of the various weather stations are as follows: 40 = Deep Well Site: Lat 34.3556, Long -106.6914 41 = South Gate Site: 34.2177, -106.7958 42 = Cerro Montosa Site: 34.3692, -106.5341 43 = Watersheds Site: 34.3892, -107.0398 44 = Rio Salado Site: 34.3489, -106.8802 45 = Bronco Well Site: 34.4068, -106.9328 46 = Langmuir Site: 33.97472 -107.1808 47 = Bosque Del Apache: **.****, ****.**** Note that Stations 40, 45, and 46 are the only stations that collect data on solar radiation. Also note that Station 47 is situated in a small clearing containing Salt Cedar within a Cottonwood canopy. The data were recorded and stored by a Campbell Scientific CR10 Datalogger. Samples were taken every "n" seconds and values averaged for the hour (where n = 3 seconds for wind speed, wind direction, and solar radiation variables; n = 30 seconds for rh, air temperature, soil temperature, and mixing ratio variables; n = 300 seconds for soil moisture variables). Numbers were stored and processed in the datalogger in binary format with 23 bit precision. Final output was rounded to a maximum of 3 decimal digits. The following variable description section provides detailed information on variables collected, units of measurement, and the format of the data section
