Hi


I tried to upload but the server provided time out every time.


Any how for the script wrf_ensemble ....... has one problem that the time used for the first do loop (time loop) is only 24 hours. This means that it reads only the first 24 times from the WRF out file instead of the whole 699 times(29 days ) in the file. Can you kindly suggest that how the do loop can be modified to include the 24 hours for each day ?


For the script UHIWind2.ncl I am getting higher temperature difference during the afternoon time which is  against the diurnal plots that I have produced. This means there is some problem on how the difference of temperature is being averaged over 29 days for 24 hours. I will be really grateful if you can provide help.

Muhammad,

It's hard to debug these kind of scripts without being able to see your data.

Can you provide the two data files that are referenced in your script?  You can use our ftp:

Dear NCL team


I am attaching two codes. The first code i.e. UHI_Wind2.ncl is run in conjunction with the attached batch script. The intension is to first obtain difference between the 2m temperature in the two files and then do an hourly average of this temperature difference for 29 days. There seems to be an issue since the difference should appear to be maximum during the night time. The wrfout files are in UTC and adding 8 hours for Singapore local time gives me the opposite result i.e the maximum difference is appearing during day time.


In the second code attached, I intend to do obtain the difference in temperature based on the land use. Here again I am having trouble with using ntimes since the plot appearing is inconsistent with the definition of UHI i.e a lowest values appearing during the noon time in the diurnal cycle.


I would be really grateful to seek help from the  NCL community
