Example code for getting MERRByS data
There are examples in Matlab and Python for accessing and analysing the data. The examples show how to:
- Download data from FTP server
- Example to read and extract data from L1b Delay-Doppler Maps
- Example to read Level 2 wind-speed
- Search data by time and location (python example only)

Data Availability and Use
Currently we are releasing Level 1B and Level 2. We are not releasing Level 0 data, except for the sample data we have made available.
We are issuing the data under a Creative Commons Licence that requires attribution and non-commercial use. Please contact us if you wish a licence that grants use for commercial purposes.
We want this service to continue beyond the lifetime of TechDemoSat-1, so we would like your help in finding the best way to exploit the data and justify flying the upgraded SGR-ReSI on future satellites to sustain this service on future satellites.
