1. The way we do satellite target prediction and MISR Local Mode planning, we designate specific locations on the surface (Lat, Lon), and find all paths that view the site.

2. The MISR overflight schedule table (PDF) gives overpass information for three sites, Abu Dhabi, Ar Ruways, Al Fujayrah.  We can provide such tabular data for any site of interest.

3. The attached MISR Imaging site maps (PDF) give MISR imaging coverage for each path that covers a site (a spearate page for each path), for nine sites: Al Jabal, Al Fujayrah, Al Dhafra, Al Qurayni, Ar Ruways, Qatar, Bahrain, Harad, and Solar Village.

3.1. The Earth is divided into 233 paths. In most cases, MISR views a given site from at least two paths, and the Terra spacecraft flies one orbit along a given path every 16 days.  So each site is imaged at least once every eight days on average.

3.2. MISR orbits north-to-south on the day side of the planet. Several sites may be imaged by MISR from the same path, and unless both fall within the same 300-km along-track region, only one can be captured in MISR Local Mode.  Recall that in Global Mode, which is "on" all the time when MISR is on the day side of the planes, 12 channels are obtained at full (275 m) resolution, whereas the blue, green, and near-ir off-nadir channels are acquired at 1.1 km resolution.  All the MISR standard products are generated from Global Mode data, so even if a site does not fall into a Local Mode box, we should have all the standard products.

3.3. In the images, the path, and all the blocks within that path, are drawn in yellow.  The extent of a Local Mode coverage region is given in purple.  In the upper left is a table giving MISR orbit, cross-track distance of the target from the sub-spacecraft line, overpass time, and date, for each overpass along that path during the Campaign. We can request Local Mode for any site of interest, provided no two sites are on the same path or are otherwise too close together.

4. I would very much like to participate in any sequence-design discussions you have next week, so we can come as close as is feasible to quantitatively testing all aspects of MISR-derived dust AOT, shape, size distribution, SSA, plume height, and radiative forcing, over land and water. Would there be any point in my participating by telecon? Olga Kalashnikova and John Martonchik might join me as well.

5. I've also attached MISR Goals and Products presentation slides (PowerPoint).
