Timing of the experiment
Due to maintenance work on the CIRPAS Twin-Otter (TO) aircraft in early April 2004, the aircraft can only be committed starting April 19, 2004. However, this is a conservative estimate and the CIRPAS flight crew has promised to attempt to make the aircraft available for guest instrument integration as early as April 12, 2004. Thus, guest investigators should be on standby for integration starting on April 12, 2004.
The timing of the experiment was supposed to coincide with the maximum
transport of Asian dust to the US West coast to ensure appreciable AOD at
2.1µm. The current timing, although late in the dust transport season
should provide dusty conditions, as supported by the 5-year analysis (1998-2002)
of the time series of 1020nm-AOD and Angstrom parameter from the AERONET
instrument at San Nicolas Island (33°N, 119°W) shown in Figure 1.
Figure 1. Time series of level 2.0 AERONET 1020nm AOD and Angstrom parameter at San Nicolas Island (33°N, 119°W).
Three of the five years shown in Figure 1 indicate the occurrence of
dust in the vertical column after DOY 110 (April 20). Hence we conclude
that an experiment starting on or before April 19 has a reasonable chance
of encountering dust conditions
