Py- ART 2 BALTRAD

[Alfonso Ladino]

Dear all,

I have been trying to use some functions from BALTRAD with Py-Art  but something seems to be wrong. I think that BALTRAD software is not connected to python. I already have installed Py-Art and BALTRAD on my machine.

This is a snipped of my code:

import pyart
import baltrad_pyart_bridge as bridge 
import _raveio

## You are using the Python ARM Radar Toolkit (Py-ART), an open source
## library for working with weather radar data. Py-ART is partly
## supported by the U.S. Department of Energy as part of the Atmospheric
## Radiation Measurement (ARM) Climate Research Facility, an Office of
## Science user facility.

      1 import pyart
----> 2 import baltrad_pyart_bridge as bridge  # routines to pass data from Py-ART and BALTRAD
      3 import _raveio   # BALTRAD's input/output module

ImportError: No module named baltrad_pyart_bridge

Any idea what is wrong?

Thanks in advance for your attention and time.

Best,

Alfonso

Alfonso,

    Is the baltrad_pyart_bridge module available?  It is not included with Py-ART or BALTRAD, but must be setup separately.  The module can be found in the pyart2baltrad repository [1].  Please note that this module has not been updated for quite some time and has no official support.

Cheers,

    - Jonathan Helmus

Dear Dr Jonathan,

I am trying to setup pyart2baltrad module but I might be doing something wrong. I am running baltrad_pyart_bridge.py from terminal and  this is the outout:

## You are using the Python ARM Radar Toolkit (Py-ART), an open source
## library for working with weather radar data. Py-ART is partly
## supported by the U.S. Department of Energy as part of the Atmospheric
## Radiation Measurement (ARM) Climate Research Facility, an Office of

Traceback (most recent call last):
  File "baltrad_pyart_bridge.py", line 47, in <module>
    raise ImportError("Can't find RAVE. Please install it.")
ImportError: Can't find RAVE. Please install it.

I think it is not conecting to BALTRAD software. Any suggestions?

Thanks again.

Best,

Alfonso.

Alfonso,

    The baltrad_pyart_bridge needs _rave, _raveio, _projection, _polarvolume, _polarscan, _polarscanparam and Proj installed [1].  Are all of those installed and available in the Python interpreter you are running the script from.  Trying out those imports one-by-one should narrow down what is missing. 

Also, note that the that module is ~3 years old any may not working with the current BALTRAD system.

Cheers,
