The link to the Perdigao Field catalog is:
http://catalog.eol.ucar.edu/perdigao
Under products you can already find images for data sets being collected but also satellite and radar images as well as weather maps which will be useful for field operations
Daily weather briefings have started, and the related slides can be found at:
http://catalog.eol.ucar.edu/perdigao/reports.
The briefings are still somewhat irregular and and not necessarily in the final format, but they provide an idea about the type of information available.
