GOES-East Surface Solar Irradiance
Operational Near real time productEstimation of the solar irradiance reaching the Earth surface derived from the 0.6 µm visible channel of the imager on board the geostationary satellite GOES.
The product is remapped onto a 0.05° regular grid and expressed in W/m2.
Identification
Acronym : GOES-E SSI
Product navigator reference :
EO:EUM:DAT:GOES:OSI-306-A-H
OSI SAF producer : Météo-France
Identifier : OSI-306-b
Acronym for EDC (APNM) : ODDLISSI
Citation : See at bottom
Characteristics
Processing level : L3
Satellite input : GOES-16/ABI
Other input : NWP outputs (water content profiles), cloud classification
Temporal sampling : 24 per day + 1 per day
Central time : 00:00, 01:00, …, 23:00 – 12:00
Timeliness :
?
The timeliness is the time elapsing from the sensing time of the last contributing file to the product dissemination to users. It is similar to the latency.
2 h
Spatial coverage : West Atlantic East Pacific : 60N-60S 135W-15W
Spatial sampling : 0.05° Lat-Lon
Projection : Cylindrical equidistant
File Formats : LML FTP Server (NetCDF4), EDC (NetCDF4), EUMETCast (NetCDF4)
Characteristics & methods : Algorithm is a physical parametrization applied separately to every pixel of a satellite image to derive an instantaneous field of the Surface Solar Irradiance. The hourly product is interpolated at rounded UT hours, by a pixel dependant temporal interpolation between two consecutive satellite images.
The value in the daily product is the integration of all the hourly values in the UT day.
The value in the daily product is the integration of all the hourly values in the UT day.
