The current GridSat product uses the operational infrared (IR) calibration information. We could provide a separate 1 km grid of the US, but it would significantly increase file sizes. The visible channel is currently 1 km of visible data, but visible data are subsampled to 4km in GridSat. could be provided, but would make the files larger. Include Cloud InformationĬloud probability, cloud parameters (cloud optical depth, cloud top pressure and temperature, etc. Providing subsampled GOES-16 data through GridSat-GOES would provide smaller files and make subsetting easier.

This would subsample GOES-16 full resolution data to the 4 km and 15 min (CONUS) or hourly (hemispherical) resolutions. The GOES-16 data stream will be large (TBs per day). Pre-GVAR data (GOES 1-7 and SMS 1-2) could be included with the same spatial and similar temporal resolutions, but with fewer available channels. The product is updated annually in January, but could incorporate additional daily/monthly/quarterly updates. The following are examples of potential updates and their effects on the dataset. Tell us what updates you’d like to see using our optional product feedback form. We are always looking for ways to improve this project. Items reported to NCEI regarding data quality will be reported here.

It is unlikely we will be able to process similar data for GOES-R series.GridSat provides information at fixed intervals, by selecting the closest scan (in time) for any given pixel. GOES data has a complex schedule with upwards of 100 scans per day providing different regions at different times. The data are provided in netCDF following the CF (Climate and Forecasting) Convention Fixed Times The IR channel data are provided in brightness temperatures (calibrated using operational coefficients) and the visible channel has been calibrated following a peer-reviewed paper. The data are provided in an equal-angle grid with 0.04 degree latitude resolution.
