Add CMS CO2 Flux dataset

[paridhi-parajuli]

Add new datasets

• CMS CO2 Flux (DAAC)
  • [x] Transformation Script
  • [x] Validation Script
  • [x] Compute SHA checksum for each cog
  • [x] Ingest to the STAC catalog with dummy collection json
  • [x] Test the E&A visualization

[Jeanne-le-Roux]

@slesaad ask for bucket access from the DAAC, so in future data can be obtained directly from the DAAC. We will also hold off of adding to the STAC catalog until the dataset is approved.

    "description": "This dataset provides the Prior for the Fossil Fuel Carbon Flux.
The NASA Carbon Monitoring System (CMS) is designed to make significant contributions in characterizing, quantifying, understanding, and predicting the evolution of global carbon sources and sinks through improved monitoring of carbon stocks and fluxes. The System will use the full range of NASA satellite observations and modeling/analysis capabilities to establish the accuracy, quantitative uncertainties, and utility of products for supporting national and international policy, regulatory, and management activities. CMS will maintain a global emphasis while providing finer scale regional information, utilizing space-based and surface-based data and will rapidly initiate generation and distribution of products both for user evaluation and to inform near-term policy development and planning.",

CMS data has been transformed (and validated for 2020 and FossilFuelPrior variable). During transformation nodata value was assigned -9999 to the -999 values. The dummy collection json mentioned above was used to create collection (id=cms-carbonflux-v3) and ingest items into dev stac. For visualization the rescale was set to 0 to 3. The E&A visualization looks like :
