Monthly Summaries of Soil Temperature and Soil Moisture in Mongolia

Summary

This data set contains soil temperature and soil moisture data from the Delger (White Bloom) site in Mongolia. Other variables include wind speed, wind direction, relative humidity, air temperature, atmospheric pressure, total rainfall accumulation, and soil heat flux. Data are in ASCII text form and Excel spreadsheet format, and were collected from June 2001 through November 2002. NSIDC currently provides these summary data via FTP; the full soil temperature and moisture data set is available from Ron Paetzold, USDA.

2. Detailed Data Description:

A Campbell Scientific CR10X-2M datalogger records day, time, battery (voltage), and internal temperature. A combination of the following below-ground sensors are attached to the datalogger: Vitel Hydra dielectric constant soil moisture and temperature sensors, Campbell 107 soil temperature sensors, and an International Thermal Instrument GHT-1C-013 soil heat flux sensor.

Sensors installed 3 m above the ground include a Licor LI200X pyranometer (solar radiation), Campbell R.M. Young 05103 wind sensor, and an Everest Interscience 4000 infrared sensor. The following are mounted 1.6 m above the ground: Vaisala HMP45C air temperature and relative humidity sensor, Campbell R.M. Young wind sensor #05103, Campbell TE525 Texas Electronics TR-525I-R2 tipping bucket rain gauge, and Everest Interscience 4000 infrared sensor.

See Soil Characteristics for a summary of soils throughout the study area.
