The Alabama Mesonet is made up of 21 combination meteorological/soil profile stations and twelve soil profile stations (no longer operational). The combination stations are also part of the USDA NRCS SCAN network. ALMNet is run by the Alabama A & M University. The original ALMNet stations (seven SCAN sites) were installed February 2002. Since June 2003 the Alabama Mesonet should really be called the Alabama/Tennessee Mesonet, since the USDA NRCS added three stations in adjacent counties north of the state line. In August 2003 one soil profile station (Bragg Farm) was converted to a SCAN site.

The ALMNet stations were a key component for bringing one portion of the Soil Moisture Experiment 2003 (SMEX '03) to Huntsville.
