GeoNEX Coincident Ground Observations (GeCGO) Data Portal

Welcome to the GeoNEX Coincident Ground Observations (GeCGO) Data Portal

The GeCGO is the subset of GeoNEX data at Terrestrial Observational Network Sites to facilitate the use of data from geostationary satellites. To make it convenient for users to get time series of GeoNEX data where ground-based observations are collected, we created GeCGO by extracting observations from the GeoNEX data over 1586 field or flux tower sites in various observation networks. To further facilitate its use, GeCGO is provided in same file format as the ORNL Terrestrial Ecology Subsetting & Visualization Services (TESViS) fixed sites subset data, formerly known as MODIS/VIIRS Subset Tools, which will be familiar to most scientists. Specifically, GeCGO data are available in CSV and JSON formats for each year. The data values were organized as 17x17, 9x9, and 5x5 grids for 0.005°, 0.01°, and 0.02° resolution, respectively. The data values represent sequences of pixels from northwest corner to southeast corner in row-major order. The data are organized into directories named after the site IDs used in the TESViS Subset.
