2008-11-21: ACC Fire/Smoke Forecasts

From Datafedwiki

A project in the CEOS Atmospheric Composition Constellation (ACC) involves smoke forecasting. The process involves use of a number of input datasets, processing algorithms, and output products. Of interest is taking the

Step 1 is to provide a standards-based interface to the output. The idea is to create an OGC Web Coverage Service (WCS) interface to the output products.

Start with the RDF AOD forecast product. What do we need to do to make it available via WCS? (see the example RDF AOD forecast file below)

Issues:

Data Format
Geographic Projection

The global 1x1 degree RDF AOD is available from Feb 12, 2008 on the regional 0.1x0.1 degree Wisconsin DNR domain is available from June 05, 2008 on the regional 0.1x0.1 degree Beijing domain is available from July 24, 2008 on The RDF output is archived in xdr (IDL portable) format

The Wildfire trajectory output is archived in machine linux binary format It's available from June 01, 2008 on The CALIPSO trajectory output was archived in machin linux binary format but was not retained due to disk space limitations.

The RDF and Wildfire trajectories are run daily and output is posted at:

Images (png) are currently available the xdr and/or binary files can be made available

Note: The CALIPSO trajectories were only run during the summer phase of ARCTAS and are currently not being run.

The tar ball (CEOS_ACC.tar) includes a readme. and:

1) Brief description:

2) Binary formated wild fire trajectories/reader

3) IDL xdr formatted Reverse Domain Filling (RDF) aerosol optical depth (AOD) forecasts/reader

The RDF forecasts are xdr files: rdf_layer_time_averaged_aod_map*.xdr
