FishVis Mapper
The FishVis Mapper is the product of an Upper Midwest and Great Lakes LCC project, “A Regional Decision Support Tool for Identifying Vulnerabilities of Riverine Habitat and Fishes to Climate Change” that developed an approach for predicting fish species occurrence under current climate conditions and project how fish species occurrence may change under future climate conditions.

Soil-Water-Balance (SWB) for estimating groundwater recharge
The Soil-Water-Balance (SWB) model has been developed to allow estimates of potential recharge to be made quickly and easily. The code calculates components of the water balance at a daily time-step by means of a modified version of the Thornthwaite-Mather soil-moisture-balance approach.
TSPROC: a general time-series processor to assist in model calibration and result summarization
TSPROC (Time Series PROCessor) is a software package designed to assist in the calibration of models by editing and distilling time series datasets into more meaningful observations to be used in the optimization objective function. TSPROC uses a simple scripting language to process and analyze time series.
