The input of satellite data into meteorological modeling for weather forecasting is well established with satellites fully dedicated to supporting its operational requirements.

The SPOT-1 to 4 satellites were the 1st generation of SPOT satellites. While SPOT-1 to 3 provided optical acquisitions from the same HRV (High Resolution Visible) sensor, SPOT-4 provided optical acquisitions from an improved HRVIR (High Resolution Visible InfraRed) sensor.
The HRV (High Resolution Visible) sensor operated in two modes, namely the Multispectral Mode and the Panchromatic Mode. Two identical HRV instruments with 3 VNIR bands and a ground resolution of 20 m could point in the cross-track direction up to 31 degrees from nadir. The swath width varied from 60 km (nadir) to 80 km when angled at the maximum limit from nadir. HRV panchromatic had spectral range between 500 nm and 730 nm (one channel) and 10 m spatial resolution.
HRVIR (High-Resolution Visible and Infrared) was an improved version of HRV with same pointing geometries and resolution capabilities as HRV. The instrument had three viewing modes: multispectral mode corresponding to HRV bands plus the SWIR with a ground resolution of 20 m, the monospectral mode corresponding to HRV with a ground resolution of 10 m and the combined mode which combined the multispectral and panchromatic modes.
