Duration: 1983 - ongoing
Dataset ID: 2100169001
Abstract:

File description including attribute definitions: Jornada_425001_npp_estimated_precipitation_data
Original investigator: Jin Yao
Data contact: Jin Yao
Duration: 1980 - 2010
Dataset ID: 210425001
Abstract:

Estimated daily precipitation is calculated for each of 15 aboveground net primary productivity (ANPP) sites located in the 5 dominant vegetation zones on the Jornada Basin. The 15 sites were formally established in 1989 as LTER Study 268, but these rainfall estimates begin in 1980 using the closest rain gauge that provides a minimum resolution of daily precipitation data. The Methodology section describes this in detail. The rain gauges are detailed inthe file raingauge_picks.csv.




File description including attribute definitions: data_JornadaStudy_127_evaporation_pan
Original investigator: Walter G Whitford
Data contact: John Anderson
Duration: 1983 - ongoing
Dataset ID: 2100127001
Abstract:

Surface evaporation is measured weekly to twice weekly using an evaporation pan compatible with standard National Weather Service evaporation measurements. Measurements are made twice per week during hot periods because of high evaporation rate. The following data is collected: number of days between measurements, beginning and ending measurement period, current, minimum, and maximum water temperature; initial water level; final water level; rainfall since last evaporation measurement, and calculated evaporation (inches).

File description including attribute definitions: data_JornadaStudy_380_jer_standard_raingage_data
Original investigator: USDA ARS Jornada Experimental Range (JER)
Data contact: David Thatcher
Duration: 1915 - ongoing
Dataset ID: 2100380001
Abstract:

The objective of this long-term project is to measure the precipitation across the entire Jornada Experimental Range. This is achieved by using a network of standard-can rain gauges to continually collect the precipitation as it occurs. The collected precipitation is then measured monthly and the results are recorded on a data sheet which is later entered into a spread sheet.

Original investigator: John Anderson
Data contact: John Anderson
Duration: 1983 - ongoing
Dataset ID: 2100126001
Abstract:

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; mean 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.

File description including attribute definitions: data_JornadaStudy_002_npp_precipitation_graduated_raingauge_monthly
Original investigator: Laura Huenneke
Data contact: John Anderson
Duration: 1989 - ongoing
Dataset ID: 210002001
Abstract:

A 4" diameter cylindric graduated rain gage (11" x 0.01" capacity) is mounted on a 4x4 inch diameter redwood post or on a wooden exclosure post next to gate at or near the 15 LTER-II NPP sites. Collection is made monthly on the day that monthly soil water content measurements are made to correlate precipitation input with belowground water content. Data is collected primarily from graduated rain gauges. However, when missing data would result otherwise, amounts from the closest rain gauge are used in order to maintain as complete a data set as possible for that site. The rain gauge used is identified with each rainfall record. Other types that may be used are the Standard Can Gauge (DSRG or dipstick rain gauge), Belfort Weigh Bucket Rain Gauge (WBRG), and Qualimetrics Tipping Bucket Rain Gauge (TBRG).
