MANE-VU Status Report on CATT and FASTNET R. Poirot, VT DEC, 9/30/04
CATT: Combined Aerosol Trajectory Tools
FASTNET: Fast Aerosol Sensing Tools for Natural Event Tracking
Both are Inter-RPO Projects, Conducted by CAPITA (R. Husar),
Managed for MANE-VU by:
MARAMA (Serpil Kayin, CATT) & NESCAUM (Gary Kleiman, FASTNET)

Within DATAFED.NET, CATT & FASTNET
are 2 of many
“Projects”
which Share Many Common
“Datasets”
which can be Viewed, Compared, Archived, Exported, Analyzed & Interpreted, using a variety of Tools &
Web-Based
“Applications”

SURF_MET bext & “dry bext” (& other met) is global.
3873 sites for this hour, 1795 (circled) reporting bext.
In “North American” domain below, there are 1870 sites with 1425 reporting visibility (blue).
Red sites are 249 US-only, ASOS-only sites for which STI provides higher resolution bext, based on access to raw, uncensored data.
