DOWNLOADING DATA VIA FTP

Data can be downloaded through a Web browser or command line via FTP. When using a Web browser, the FTP link first directs you to an Optional Registration Form that if filled out, will allow you to receive notifications about updates or processing changes related to that specific data set. After completing the Optional Registration Form, the FTP directory becomes available. For additional help downloading data through an FTP client, go to the How to access data using an FTP client support page.

Monthly Summaries of Soil Temperature and Soil Moisture in Mongolia, Version 1

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.

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.
