   With the exception of Polk county, the source of all soil property attributes 
   is the Iowa Soil Properties and Interpretations Database (ISPAID). Soil Survey 
   Geographic Database (SSURGO, version 2) and Map Unit Interpretation Record 
   (MUIR) databases were used to populate a selected set of soil property 
   attributes for Polk county. Due to dissimilarity between these data sets, 
   attribute values for Polk county may differ from those of similar soils 
   observed in neighboring counties. 

   Areas of soils of a single taxonomic class rarely, if ever, can be mapped 
   without including areas of soils of other taxonomic classes. Consequently, 
   every map unit is made up of the soil or soils for which it is named and some 
   soils that belong to other taxonomic classes. Please see 
   'iowa_soils_metadata.pdf' for more details.

Group: Summary

   The Soil Moisture Experiment 2002 (SMEX02) took place in Ames, Iowa USA 
   between 25 June and 12 July 2002. The NASA Land Surface Hydrology Data Archive 
   maintains an archive of soils and land cover characteristics for SMEX02. 
   SMEX02 studies are designed to evaluate the accuracy of AMSR-E soil moisture 
   data specific to the SMEX02 study areas, and SMEX02 provided the unique 
   opportunity to test microwave soil moisture retrieval over agricultural land 
   cover. The Soils Database includes Environmental Systems Research Institute 
   (ESRI) shapefiles containing geographic information such as railroads, roads, 
   and stream locations; drainage features; political boundaries; and soil 
   classifications. Data for the following 10 Iowa counties are included in this 
   data set: Boone, Dallas, Franklin, Hamilton, Hardin, Jasper, Marshall, Polk, 
   Story, and Wright. These data were created by appending existing county 
   digital soils data provided by the Iowa Cooperative Soil Survey (ICCS) and 
   clipping them by the SMEX02 project area boundary; thus, the dates of data 
   acquisition are highly variable. The entire data set is 293 MB. Data are 
   available via FTP.

   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.
