Climate dataset or project
Daily summary values of averages of readings of the following parameters are made which are based on data recorded on a Campbell CR10(X) data logger: maximum, minimum, and average air temperature; maximum and minimum relative humidity; total precipitation; average wind speed; maximum wind speed; average wind direction; total incoming solar radiation; average soil temperature at 5cm and 20cm; me
an dew temperature. From 1983 - 5 June 1991, readings on which daily averages are based were made at 12 second intervals. From 6 June 1991 to present, readings on which daily averages are based are made at 10 second intervals.

Jornada LTER climatalogical station on the Jornada basin. Weather station location:
deg min sec UTM: 331192.4E 3599474N WGS84, Zone 13
LAT 32 31 17
LONG 106 47 50
Hourly and Daily Summary climate data is collected for Wind Speed, Wind Direction, Solar Radiation, Relative Humidity, Precipitation, Air Temperature, and Soil Temperature.
See LTER Weather Station Documentation Directory for complete description of weather station.
In short, though, from 1983 - May 1991 hourly averages of readings are made at 12 second intervals for each instrument and are recorded using a data logger (AUTODATA10/5). From June 1991 until present, hourly averages of readings are made at 10 second intervals for each instrument and are recorded using a Campbell Scientific 10x datalogger.
Beginning in 1983 the following parameters have been collected: Wind Speed, Wind Direction, Solar Radiation, Relative Humidity, Precipitation, Temperature of Air, and Temperature of soil at Surface, 1cm, 5cm, 20cm, 50cm, 100cm, and 200cm.
Temperature data was acquired using a mechanical chart recorder of soil temperatures at 5 cm and 20 cm soil depths at a site approximately 20' west of the Upper Trailer on the Jornada.
In the spring of 1982, as part of the establishment of the Jornada Long-Term Ecological Research site in southern New Mexico, a 135 ha portion of a 1500 ha, internally drained, watershed was exclos
ed from grazing by domestic livestock. Prior to exclosure the watershed, as well as the rest of the Jornada basin, had been moderately to heavily grazed for the past 100 years. Concurrent with grazing, the vegetation had undergone a dramatic change from desert grassland, with an almost continuous cover of C4 perennial grasses, to isolated patches of the original grassland in a mosaic with desert shrub dominated plant communities (Buffington and Herbel, 1965).
The exclosure lies along a northeast facing piedmont slope at the base of a steep isolated mountain peak, and covers a variety of component landforms from the foot of the mountain to the basin floor. The northeast side of the exclosure is immediately upslope of the College Playa located near the NMSU College Ranch.
Three parallel transects (2.7 km in length) run from the middle of the College Playa up into the foot of Mt. Summerford. The Control transect is to the west, the Treatment transect on the east side of the Control transect, and the Alternate Control to the east of the Treatment transect. Each transect is 30 meters wide with a 45 meter buffer zone between each transect. The Treatment transect was treated annually until 1987 with NHNO3 in a concentration equal to 10g N/m2. The station markers at 30 meter intervals along each transect.
Precipitation is recorded weekly at each of the 91 sampling stations located 30m apart along the LTER-I Control Transect from a direct- reading rain-gauge attached to the west cross-arm of the station marker.
Climate data collected at USDA Jornada Experimental Range Headquarters which is a NOAA weather station.
Daily data has been collected since 1914 for minimum and maximum air temperature as well as daily precipitation. Pan evaporation data was collection from January 1956 through August 1979.
Monthly summary of precipitation and air temperature data collected daily from standard U.S. climatological service instruments located at USDA Jornada Experimental Range Headquarters.

Soil temperature data was acquired using a mechanical chart recorder of soil temperatures with thermistors at 5 cm and 20 cm soil depths at a site approximately 20 feet west of the Upper Trailer on the Jornada.
