Context

Purpose

Explore MODIS satellite imagery and wildfire data that is open and free for scientific use.

Sensor description

The MOD021KM product contains calibrated and geolocated at-aperture radiances for 36 discrete bands located in the 0.4 to 14.4 micron region of the electromagnetic spectrum.

Highlights

  • Use satpy to load, visualise, and regrid MODIS level 1B data.

  • Fetch a fire database containing some 497364 fires from 2020.

  • Visualisation of fire pixels from the database.

  • Visualisation of the fire pixels alongside bands from the MODIS satellite data.
