The dust conditions over the Sahara for the duration of the experiment is best seen in the NAAPS/Satellite Composite Loop which shows TOMS, NAAPS, DREAM, and SeaWiFS data in four-panel plots.

Also look at the standard NAAPS product for the Sahara   and the   X-Section Product

Also look at the standard NOGAPS product for the Sahara

The dust conditions over the Atlantic for the duration of the experiment is best seen in the NAAPS/Satellite Composite Loop which shows TOMS, NAAPS, GOES, and SeaWiFS data in four-panel plots and in NAAPS Cross-section Loop which shows NAAPS AOD and cross-sections of dust concentration over the Tropical Atlantic and Caribbea and Caribbean.

A global view is given in this loop of NAAPS AOD and TOMS AI.

View the NAAPS/Satellite comparisons listed above in DUST ANALYSIS.

NAAPS is compared with NOAA/NESDIS AOD for the duration of the experiment in loop of NAAPS/NOAA-AOD Global Pixel Comparison Look at the 2nd and 3rd boxes on the second line: The second is for the West Atlantic; the 3rd is for the East Atlantic.

Successive NAAPS forecasts valid for the same time (e.g. 120-h, 96-h, ... 0-h)are intercompared in these loops:

NAAPS forecast comparison for July 3 (DE2)
NAAPS forecast comparison for July 5 (DE3)
NAAPS forecast comparison for July 11 (DE4)
NAAPS forecast comparison for July 16 (DE5)

NAAPS comparison for DE1 - DE6 shows NAAPS dust OD for the seven dust events at the time that the trailing tropical wave crossed the African coast (15W): June 25, 28, July 2, 7, 13, 18, and 22. During the experiment, only six events were identified. Since then, a seventh event, on June 28, has been identified. It will be called `DE1B'.
