Re: hybrid sigma-pressure levels to altitude in meters

The program profile.F should help you get the variables profiles as a function of height. so I tried and it gave the variables profiles as a function of pressure, how to convert pressure to height in meters?

Re: Export RH2m from ARL GDAS data

Dimension range can also be given by min/max indexes, or by exactly min/max longitude/latitude (only for lonlat projection data). #Set dimension range by indexes data = f['T02M'][tidx,lidx,80:100,20:50] #Set dimension range by lon/lat data = f['T02M'][tidx,lidx,[-10,10],[20,50]] Why does it give me...

Re: hybrid sigma-pressure levels to altitude in meters

The program profile.F should help you get the variables profiles as a function of height. I only have executable profile.exe where I can find source code to edit it and compile? Is there any documentation on the format of gdas files so I can write my program to extract desired values at desired hei...

hybrid sigma-pressure levels to altitude in meters

Is there a way (formula) to convert hybrid sigma-pressure levels to altitude in meters? What I am trying to do is to get wind direction and speed at certain height (meters) from file *gdas0p5.

Merging dose files

Hello! I'm trying to simulate several different (kt, time, location) nuclear explosions. I make, say, 3 different runs with different location, start time, then count dose from those runs with different yield(kt). In the end I have 3 files: dose0, dose1, dose2. Now I want to merge them into one file...
