All:

I've been curious about this, myself, given that the DSSAT models have been used in many climate change studies.  Whatever system is used, it should be one that gives good results for winter wheat.

Subject: Calender issue for climate change study

Dear DSSAT users,

We have plans to do yield estimation using future climate change scenario.
We have already downscaled  the GCM data using an RCM (PRECIS) for our
region. The climate change models use 30 days/month calender ie 360
days/year while DSSAT uses Gregorian calender. One option to overcome this
is to keep the 360 days as Julian days and the remaining 5/6 days can be
copied from the 360th day keeping the rainfall alone as ZERO.

Is there any other specific methodology available to convert the 360 days
calender to Gregorian calender. Kindly help us to proceed further.
