  • Due date set to 11/30/2018

The PyCAMA tool is now running for about 6 months on (near) operational data for most products. This also means that you have some experience with the output of PyCAMA and the reports on

I think that this is a good moment to review the settings we use in PyCAMA. In particular:

  • Are there parameters that can be removed from the list?
  • Are there graphs that should be removed from the output? Specifically we can easily remove a parameter from the scatter density plots. Is there a parameter that doesn't add anything to those graphs?
  • Are there parameters that should be monitored, but can be excluded from the L3 plots?
  • Are the ranges of the histograms appropriate?
  • Are there other errors in the output?
  • Are we missing parameters?

This issue is for the configuration of PyCAMA. Feature requests can be added as issues to this project.

Added the configuration file generator for PyCAMA to show what the starting point is.

Hi Maarten

There is one variable for the OFFL report we want to include here as well as in the time dependent reports, namely the "effective_albedo". Range (-0.1 to 1.3)

I suggest to skip AMF trueness completely from the NRTI report - it is a function of SZA and this how it looks like in the report.

Moreover the data ranges for the following variables might be adapted:
O3 vertical column precision [mol/m^2]: 0 - 0.015 for NRTI and 0 - 0.01 for OFFL
Fitting RMS 0 - 0.006 for both
shift: +0.03 and stretch: + 0.01
Effective temperature NRTI 200 - 280 [K] no change for OFFL
O3 ghost column 0-0.01 only available in OFFL

  • Target version set to PyCAMA 0.9.0

Thank you Klaus-Peter for hte feedback. I've incorporated your requests in the upcoming version.

All others: please let me know ASAP if you have changes for the PyCAMA configuration.

#8 Updated by Maarten Sneep 9 months ago

Some of you requested a different range for the histogram and the world-plot. This is already possible. If you want to use this, please update the configuration to include a 'map_range' key, with the desired range for your world plot. If not available, the data_range key will be used.

  • Status changed from New to Closed
  • % Done changed from 0 to 100

As PyCAMA 0.9.0 has been released I'm closing this issue here. A new request will be made for PyCAMA 0.10.0, which will likely be the version used for collection 2 reprocessing and the start for long-term monitoring.
