MODIS/Terra Thermal Bands Daily L2G Global 1km SIN Grid Day NRT provides daily brightness temperature measurements from three thermal infrared bands (20, 31, and 32) on a global 1-kilometer grid. The product includes band 20 albedo data and is produced by the LANCEMODIS organization using the MODIS instrument on NASA's Terra satellite. It is delivered in a Sinusoidal projection.
Use Cases
- Modeling land surface temperature dynamics using brightness temperature from bands 31 and 32.
- Analyzing thermal anomalies and fire detection by comparing daily brightness temperature values across bands.
- Studying surface albedo interactions with thermal radiation using the provided band 20 albedo data.
- Monitoring diurnal thermal cycles by tracking the daily time-series of brightness temperature measurements.
- Calibrating other thermal sensors by comparing brightness temperature values from the MODIS thermal bands.
Strengths
- Provides data from three specific thermal infrared bands (20, 31, 32).
