Abstract
Satellite derived images of boundary layer properties are generated from AVHRR data collected during SHAREM 110 (6 February-18 February 1995) and during Naval Postgraduate School cruise (16 May 1995) for comparison with in- situ data. The technique, proposed by Kren (1987), verified by Smolinski (1988) and applied by Walsh (1994) uses NOAA AVHRR channels 1, 2, 4 and 5, and the relationship between radiative extinction and relative humidity and atmospheric absorption and column water vapor. The percent of total atmospheric water vapor contained in the MABL is determined, via the method C Walsh (1994), and is provided to the algorithm. The technique successfully mapped boundary layer height for two different coastal regimes, Persian Gulf and Monterey Bay region. The method failed in the Gulf of Oman region for a case strongly affected by continental influences containing a large concentration of land aerosols. The results also show that the algorithm is closely tied to the sea surface temperature and can only retrieve the layer depth most closely associated with the surface. Therefore, this technique cannot indicate the presence of elevated layers not associated with the surface.
