2\05 ISS On-Orbit Status 05-02-2003
Part 2 of 2

Today's targets for the CEO (crew earth observations program) were Red
Basin, Sechuan, China (Dynamic event. A major break in the weather has
produced the best viewing of inland China this winter. The circular 
Red Basin is the center of China's largest province with 115 million 
people, most of whom live in the basin. With major industrial cities 
and open fires for cooking, air quality is significantly degraded 
under high pressure conditions. The basin has the longest continuous 
record of air clarity measurements [skyward-looking radiometers] on 
Earth [since the 1940s]. Any views of the region, clear or with smog 
buildup, are of interest to US scientists), Beijing, China (nadir 
pass; ESC [electronic camera system].  Trying to get the entire urban 
region in one or two views), Delhi, India (nadir pass; ESC. The city 
lies on both banks of the Yamuna River.  Atmospheric haze appears to 
be returning in the Ganges basinlooking right for oblique views), Rift 
Valley lakes, east Africa (Dynamic event. For a few weeks a year, 
equatorial Africa experiences low cloud cover. Look right of track for 
glint/near glint views of: Lake Tanganyika [geological structures], 
then Lake Victoria [coastlines], then Lake Turkana [coastline, esp. 
Omo River delta at the north end]. The delta is a permanent Earth Obs 
monitoring site since it fluctuates in size significantly as lake 
levels change. [Past handheld imagery shows that Lake Turkana rises 
quickly during El Nino events, whereas the Nile River immediately 
north experiences below-normal flow, an inconsistency that is not yet 
understood. It would be very interesting to test the response of the 
Lake Turkana coastline under the present El Nino with your imagery.]), 
Addis Ababa, Ethiopia (nadir pass; ESC), Tashkent, Uzbekistan (just 
left of track, this capital city [and most other central Asian cities] 
lies on the wetter lower slopes of the Tien Shan Mts., in what is 
otherwise an arid part of the world), Sabancaya landslide, Peru (nadir 
pass. This hazard site is difficult to see, but a mapping swath for 30 
secs under track will capture it), Panama (Dynamic event. Request for 
panoramic views [obliques left and right] and then detailed nadir 
views of this poorly photographed region), and El Paso, Texas (nadir 
pass; ESC).
