hi I am doing some diurnal analysis with WRF output data so need to know the time information. I know the WRF outputs all are reported at GMT time. My question is, is the curving of international dateline taken into account in the grids? or the time zones are separated simply by straight vertical lines at each 15 degree parallel to the meridian?

Thank you so much for your response.
 
Hi,
Are you asking about a specific application in WRF, or is this question referring to WRF, in general? There are no time zones in WRF. There are domains, and it's up to the user to determine the difference in time from UTC. If I'm not answering your question, please provide more detail. Thanks!
 
Thank you for your response. I think you got my question right. My question is about how to convert the UTC time (reported by WRF) to local time at each grid cell. So, it looks like it is up to the user as to how he/she wants to convert the UTC time to local time as you said. But I am still puzzled. WRF does not know the local time of a grid cell but it knows the UTC time of that grid cell. Wow. It seems rather un-intuitive to me. :D
