# COMS-1 Meteorological Satellite Tools

> COMS-1 Meteorological Satellite Tools parse LRIT and HRIT files carried by the satellite's L-band downlinks. The scripts display xRIT headers, extract Meteorological Imager segments and additional data, create images and overlays, and handle decryption key messages. Sample xRIT files and decoded images accompany the tools.
