Observation Database for Exploring the footprint representation of microwave radiance observations in an Arctic limited-area data assimilation system

Basic matplotlib visualization for observational databases.
Archive files, readme, and visualisation script are attached.

The python script visualizes the statistics related to observation 
minus background departures for AMSU-A and MHS sensors using
the default and footprint observation operators in the AROME-Arctic data assimilation system.
