Data Conversions and Subsets

Standard Services

NetCDF conversion (Need feedback from JPL

regarding level of CF1 compliance)

Data Subsets Level 2: standard, support (e.g., averaging

kernels)

cloud cleared radiances

Other data subset services

OpenDAP Binary format via http (2.5 granules/sec of a

dust flag subset)

CEOP Subsets

Future Services

We are investigating Buffer format

Coordinated Energy and Water Cycle Observations Project (CEOP)

37 2.5°x2.5° sites around the globe

subsets of 5 larger monsoonal regions are under development

  • Global maps of BT_diff_SO2 at 0.1 deg, CO at 0.33 deg, and false-color RGB at 3-km

resolution, as output from the Near-Real-Time flow are utilized in a new Web Map service.

  • It is an experimental "quick-look" for scientists working on volcanic eruptions
  • Possible interest from NOAA Satellite Analysis Branch
  • Web Map Service access

– Clients: IDV 2.6, McIDAS-V*, GoogleEarth*, Q-GIS, et al. – Web Browser: Users can bookmark any region for repeated views

  • Web Coverage Service (geotiff) access

– Clients: Matlab, IDL, …

(*Still working on issues with some clients)

Modern Era Retrospective-analysis for Research and Applications (MERRA)

Three-dimensional analyses are generated every

6 hours

Three dimensional diagnostics, describing the

radiative and physical properties of the atmosphere, are 3-hourly

3 separate streams

  • 1979 – 1989
  • 1989 – 1998
  • 1998 – present (Currently, the AIRS era is

complete through Dec 2003)

All data will be available by November 2009.
