Hi Julie,

METRo needs in fact at least 2 atmospheric forecast.

I have updated the code so there is a check at the initialization. Now 
your example exits with the following error:
EXECUTION  : METRO_PREPROCESS_VALIDATE_INPUT module: start execution
STOP       : METRo needs more than one forecast date! Exiting


Commits 140 includes this check. See
http://svn.gna.org/viewcvs/metro/metro/trunk/src/frontend/executable_module/metro_preprocess_validate_input.py?rev=140&view=log

I have also updated the documentation. See
http://documentation.wikia.com/wiki/Input_forecast_%28METRo%29#Contents

Fix will be included in METRo 3.1.0

Cheers!

Miguel
