GEO-LEO contains the products pertaining to the inter-satellite calibration between Geostationary Orbit (GEO) satellite Low-earth Orbit (LEO) satellite. NOAA geostationary satellites include NOAA GOES-11, GOES-12 and GOES-13. Other geostationary satellites includes MET-7,MET-9,FY2C/2D and MTS01. Low-earth Orbit (LEO) satellite are Aqua AIRS and Metop-A IASI. The products provided here are calibration coefficient (slope,offset,covariance), and bias monitoring (correction validate,standard scenes, homogeneous scenes, 2D distribution), as well as ancillary information(radiance scattering, spatial distribution, spectra distribution).
