Group: Summary

   This work is part of the Soil Moisture Experiment (SMEX) project. This data 
   set provides data from various sensors on the Soil Climate Analysis Network 
   (SCAN) station number 2031, located near Ames, Iowa, USA. The data include: 
   hourly and daily recordings of precipitation, air temperature, solar 
   radiation, wind speed, relative humidity, soil moisture, and soil temperature.

   The station houses numerous sensors that automatically record data. Sensors 
   include: global precipitation sensor, thermistor, thin film capacitance-type 
   sensor, anemometer, pyranometer, pressure sensor, and a frequency-shift 
   dielectric measuring device. Units of measurement vary, depending on the type 
   of sensor. Data are uploaded by meteor burst telemetry to the Natural 
   Resources Conservation Service (NRCS) Data Processing Center in Portland, 
   Oregon.

   The NRCS has been operating this SCAN station since 23 September 2001, but 
   this data set covers only the time period of interest to the Soil Moisture 
   Experiments 2002 (SMEX02) campaign, 1 June 2002 through 31 August 2002. Data 
   are available via FTP in two text files, one for hourly data, the other for 
   daily data.

   These data were collected as part of a validation study for the Advanced 
   Microwave Scanning Radiometer - Earth Observing System (AMSR-E). AMSR-E is a 
   mission instrument launched aboard NASA's Aqua Satellite on 04 May 2002. 
   AMSR-E validation studies linked to SMEX are designed to evaluate the accuracy 
   of AMSR-E soil moisture data. Specific validation objectives include assessing 
   and refining soil moisture algorithm performance; verifying soil moisture 
   estimation accuracy; investigating the effects of vegetation, surface 
   temperature, topography, and soil texture on soil moisture accuracy; and 
   determining the regions that are useful for AMSR-E soil moisture measurements.
