1. Brief  description of the problem:

Some coastal grid points may display unrealistic of Tmax . All of  the spurious Tmax points are flagged as being ocean points based on the atmosphere land-sea mask.

2. Recommendation:

Use Tmax  over land points only based on POAMA's* land sea mask to eliminate the spurious Tmax values.

* POAMA stands for Predictive Ocean Atmosphere Model for Australia.
