Script runs out of memory

Hello, To briefly summarize, my script tries to read the temperature values at a bunch of weather stations (76) throughout the year. So for each day I create adde urls , access the temperature value using the url and write them to a file. The problem is my script cannot handle more than ~50 days at ...

Script to grab data from all locations in the area file.

Hello, I was wondering if there is a way to loop over all the locations in an area file and grab the data from each of them. If so, how memory intensive is the process going to be? (Eventually, I plan to do this for all 366 days of the year 2012) I understand that this depends on the size of the are...

Re: Subtracting Images

Tom, Thanks for the clarification. We were able to figure out the same using the data-probe tool present in McIDAS-V where its readout was matching with the first value present in the array. To compensate for the scaling, I divide the value by 10. Thank you for helping with my questions, I now have ...

Re: Subtracting Images

The ADDE servers can return a very small region (say, 1x1 -- although the servers will return a 1x4 set of data, since the number of elements must be a mulitple of 4) and you can request the data at a particular latitude / longitude coordinate so your program/script would not have to do any navigat...

Re: Subtracting Images

Hello Bob, Firstly, thanks for responding quickly. From your reply, it seems like the netcdf files won't be having any navigational data in them ( Unlike the area files with their NAV block).
