[gradsusr] Fwd: How to use NCEP/NCAR reanalysis data

[Djordje Romanic]

Dear Users,

Please, anyone... can you confirm me will the following command averaged the
u wind component for the time period from jan1948 to dec2000 (at 500 mb
hight) and for the whole globe?

sdfopen
http://monsoondata.org:9090/dods/_expr_{rean3d}{ave(u,t=1jan1948,t=31dec2000)}{0:360,-90:90,500:500,jan1948,dec2000}

Please, any comment would be very valuable for me.

Thanks in advance,

Djordje

Dear All,

Please would you be so kind to explain me how to perform the following
analysis. Namely, using the NCEP/NCAR reanalysis data for u and v wind
components (for any hight, say, at 500 mb) for the period from 1948 to 2000
I would like to:

   - I would like to average all monthly averages for the u wind
   component, for the above mentioned time period, and to draw it for the
   Europe,
   - I would like to average all monthly averages for the v wind
   component, for the above mentioned time period, and to draw it for the
   Europe.

As You can see, I would like to see the average zonal and meridional wind
components for the Europe in the [1948,2000] period.

Please, could you give me instructions how to perform these analyses using
GrADS, i.e. what commands should I use?

Thanks in advance.

Best regards,

Djordje
