The Ag Data Commons is migrating

The Ag Data Commons is migrating to a new institutional portal on Figshare. The current system is available for search and download only. The new platform is open for submission with assistance from Ag Data Commons curators. Please contact NAL-ADC-Curator@usda.gov, if you need to publish or update your datasets.

Soil Temperature and Moisture Model

Purpose: The STM2 model predicts the soil temperature and moisture conditions based on very limited user inputs. The input requirements are:

  1. A general soil characterization (soil texture and organic matter content)
  2. Daily weather information limited to maximum and minimum air temperatures with daily precipitation.

There is a help file that describes the program included in the file list below (STM2_description.doc).

Disclaimer: The USDA-ARS makes no warranties as to the merchantability or fitness of STM2 for any particular purpose, or any other warranties expressed or implied. Since some portions of STM2 have been validated with only limited data sets, it should not be used to make operational management decisions. The USDA-ARS is not liable for any damages resulting from the use or misuse of STM2, its output and its accompanying documentation.

STM2 was written in Java, and therefore can run on multiple platforms (e.g. Windows, Mac, Unix).
