Reference proper isobaric level for temperature
Show older comments
I have a grib2 dataset I am using and want to pull a specific isobaric level for temperature but I am not totally sure I have the correct one (temperatures are too low). Here is what I am doing:
nc=ncgeodataset('DD.20180522_CY.12_FH.000_DF.GR2')
lon=nc{'lon'}(:);
lat=nc{'lat'}(:);
Ti=nc{'Temperature_isobaric'}(:);%[K] temperature at various isobaric levels
Temp850=Ti(:,6,y,x); %pulls the temperature data at 850mb with y=a preset lat and x=present lon span
On the website linked below,
it says 850mb temperature is the 6th height but I can't figure out why my temperatures are much lower than they should be. Any help would be appreciated.

Make it easy for people to help you by attaching 'DD.20180522_CY.12_FH.000_DF.GR2' in a .zip file with the paper clip icon. Otherwise they may not bother.

Ummm... I don't think that can be attached.
