Description

IDV is a geoscience display and analysis software system with many of the standard data displays that other Unidata software (e.g. GEMPAK and McIDAS) provide. It brings together the ability to display and work with satellite imagery, gridded data (for example, numerical weather prediction model output), surface observations, balloon soundings, NWS WSR-88D Level II and Level III RADAR data, and NOAA National Profiler Network data, all within a unified interface. It also provides 3-D views of the earth system and allows users to interactively slice, dice, and probe the data, creating cross-sections, profiles, animations and value read-outs of multi-dimensional data sets.

Usage

Upcoming modulesystem change alert!

Due to large number of applications and their versions it is not practical to keep them explicitly listed at our wiki pages. Therefore an upgrade of modulefiles is underway. A feature of this upgrade will be the existence of default module for every application. This default choice does not need version number and it will load some (usually latest) version.

You can test the new version now by adding a line

source /cvmfs/software.metacentrum.cz/modulefiles/5.1.0/loadmodules

to your script before loading a module. Then, you can list all versions of idv and load default version of idv as

module avail idv/ # list available modules
module load idv   # load (default) module


If you wish to keep up to the current system, it is still possible. Simply list all modules by

module avail idv

and choose explicit version you want to use.

  • tunnelling the graphical display, log into a MetaCentrum frontend:
$ ssh -X skirit.metacentrum.cz
  • run the application either locally on the frontend or (better) on a computing node:
    • running on a computing node:
      • ask the scheduler for an interactive job -- specify the number of processors you intend to use (the "Y" attribute), as well the amount of memory necessary (the "Z" attribute). Do not forget to tunnel the graphical display again via the "-X" option:
$ qsub -I -X -l nodes=1:ppn=Y -l mem=Zg
  • load the application module and run the IDV:
skirit$ module add idv-3.1
skirit$ runIDV  # or: simpleIDV
  • running on a frontend:
  • load the application module and run the IDV:
skirit$ module add idv-3.1
skirit$ runIDV  # or: simpleIDV

Notice: This application use or needs GUI – graphical interface. To use the application in graphical mode see Remote desktop or X-Window.
