The Geospatial Climate Outlook Forecasting Tool (GeoCOF) is a statistical software tool for producing forecasts of seasonal rainfall and other climate variables. Through a user-friendly graphical interface, GeoCOF facilitates multiple-linear regression modeling, identification of potential predictors (e.g. regional sea surface temperatures), and forecast model skill assessments. Graphical outputs are designed to support regional climate outlook forums, such as through presentation of forecasts using tercile categories and maps.
GeoCOF is a streamlined way of implementing the "SYSTAT” process with automation of various statistical analyses, and improved functions for digitizing predictor ocean basins and for defining homogenous climate zones.
You can get the latest version of GeoCOF here download the GeoCOF here.
A manual is available here to guide you through the process of using the tool to generate seasonal rainfall forecasts.
SST Data for GeoCOF
CHC currently supports GeoCOF-compatible (.bil) versions of three gridded SST data sets
Current and historical North American Multi-Model Ensemble (NMME) forecasts for seasonal mean SST. Click here for more about NMME. Click here to access the GeoCOF-compatible NMME data. From this link are directories named “2019.MM,” where MM indicates the month the forecast was initialized. Each contains a set of NMME ensemble mean 1982-2018 hindcasts and 2019 forecasts. These ensemble means are based on the models that have released forecasts during the first ten days of the month.
