<div><font color="#17365D">I am working on a study for a client. As part of this study, I need to download GCM data for several GCM models (from AR4) and calculate 30-year averages for precipitation and temperature for historic period (1970-2000) and future
period (2035-2065). I am using emission scenario SRES A1B for my analysis. I am using GraDs and monmask commands to calculate the long-term averages. The client wanted me to superimpose actual meteorologic averages collected for the historic period over
the model results for the same historic period. When I did that, we noticed that GCMs are severely under predicting both precipitation values and temperature values. I explained to the client why and how we should not compare GCM output with real-time observations
for a local region because the scale of GCM results does not compare well with meteorologic records collected at a local scale. However, they are still not convinced that GCM models would under predict the results so much. They wanted me to contact a specialist
that deals with GCM models. </font></div>

<div><font color="#17365D">I am not sure how I should address the client’s concern. I know that a lot of members of this community are experts in GCM models. Can someone help me with this question? You can send an email directly to my email address at tummuris(at)cdm.com.
I appreciate any help.</font></div>
