Hello, everyone. I'm working with forecast from GFS 0.5x0.5 Degree (I'm working with GrADS 2.0.a9), but I've got some problems with environment dimensions. When I write ga-> set lat 45.7 GrADS replay: LAT set to 46 46 Someone knows what should I do to get the forecast at lat 45.7? There are any posibility to interpolate data? Thank you so much!!
