For example, a fire must have an active area ≥ 100m 2 to enable detection by a satellite pixel with an effective resolution of 1km.
With that being said, traditional satellite fire detection algorithms currently used with the MODIS, VIIRS and GOES fire products begin to respond to active fires occupying a relatively small fraction (≥ 0.01 %) of the pixel footprint (assuming an average fire temperature of ≥ 800 K). Fire detection is largely a function of spatial resolution, with coarser data sets typically requiring larger and/or more intense fires for a successful detection compared to higher spatial resolution ones that can resolve smaller and/or less intense fires. There isn’t an absolute size above which one can expect a fire detection from satellites.

Other possible updates include: improved coverage by expanding the GOES inventory (currently, gaps exist in the CLASS archive) and expand to the predecessor to the GOES Imager: GOES VISSR, which would expand coverage back to the 1980s. However, future efforts are planned to include some basic cloud information (cloud probability, temperature, etc.). Currently, the data are limited to variables including the observations from the GOES satellites: 5 total channels. The data are provided hourly, with all data mapping to the nearest hour. Data are mapped to a region spanning the view of GOES East and West (150 deg East to 5 deg East). The data are provided near the original spatial resolution of the infrared channels (4 km) on an equal angle grid (0.04 degrees). This is similar to the current GridSat-B1 CDR, but at a higher spatial and temporal resolution. GridSat GOES represents a reformatted, remapped and calibrated GOES brightness temperatures and reflectance provided in Climate and Forecasting (CF)-compliant netCDF format. The National Centers for Environmental Information in partnership with the Cooperative Institute for Climate and Satellites - North Carolina is reprocessing the GOES (Geostationary Operational Environmental Satellite) Variable (GVAR) period of record: 1994-2015.
