Operational weather forecast+influence functions

Pedro February, 2005

Sounding network

G. Fisch February, 2005

• Methodology to be used during FIRE experimentally

and later on during BARCA (Longo et al., 2004):

– Backward trajectories runs from regional scale

forecast;

– Footprints helping to choose the most significant

regions for flight measurements.

– Forecasts available at http://www.master.iag.usp.br
