Removal of Content Advisory - April 2024

Advisory to Gridpoint Statistical Interpolation (GSI) users: As of the beginning of April 2024, all support assets for Gridpoint Statistical Interpolation (GSI) will be removed from the DTC website. Users should download all reference materials of interest prior to April 2024.

Gridpoint Statistical Interpolation (GSI) | Citation and Publications

Citation

The GSI code management and support were made available through 31 December 2021 through a community GSI effort jointly led by the Developmental Testbed Center (DTC) and the National Centers for Environmental Prediction (NCEP) Environmental Modeling Center (EMC), in collaboration with other GSI developers. We recommend for those who use the community released GSI, the GSI User's Guide, and other DTC GSI services, please refer to this community GSI effort in their work and publications.
