Howdy ferreteers, I have been converting the variance script I found from the initial install for use with my data sets. Unfortunately, I have a problem with the data sets being unequal in size as well as not on the same gridpts and different resolutions: ************************************************************ ./TRMM_SST_concat.nc (resolution of 0.25km or about a quarter degree) name title I J K L SST SST 1:1440 1:320 ... 1:762 X=0E:0E(360) Y=-40:40 Scattereometer.nc (1 degree resolution) name title I J K L U zonal pseudostress at 10m 1:360 1:171 ... 1:839 X=0.5W(-0.5):0.5W Y=85.5S:85.5N V meridional pseudostress at 10m 1:360 1:171 ... 1:839 X=0.5W(-0.5):0.5W Y=85.5S:85.5N precip97_01.nc (1 degree resolution) name title I J K L PRECIP Daily Precip 1:360 1:180 ... 1:1704 X=0E:0E(360) Y=90S:90N ************************************************************ I thought the answer would be to specify my regions with x, y and tlimits in my script: *********************************************************** Set mode interpolate use "/rlp/scocks/qscat_99_01mask.nc" use "/rlp/scocks/precip97_01.nc" set window/clear/size=0.75/aspect=0.8 Set Region/x=120e:70w/y=60s:60n let magnitude=(U[d=1]^2+V[d=1]^2)^0.25 let uwnd=U[d=1]/magnitude; let vwnd=V[d=1]/magnitude let r=6.38e6 ; let omega=7.292e-5 ; let d2r=atan(1.0)/45 let Div=(uwnd[x=@ddc]+vwnd[y=@ddc]-(vwnd/r)*tan(y[d=1,g=u]*d2r)) LET p = Precip[d=2, x=120e:70w, y=35s:35n]; LET q = Div[d=1, x=120e:70w, y=35s:35n] ***************************************************************** But I got the following error from the last step: l **ERROR: inconsistent sizes of data regions: X axis Variable 2 is I=171:181 expression is I=171:180 I specifically looked for this type of problem on the archive and didn't see it. Does anyone know how to solve this problem? SCOCKS TAMU
