After a two day open workshop we were 7 pytrollers from Finland, Iceland and Sweden staying till the end of week working together on some pressing issues. See below for a summary of achievements. If you would like to contribute actively with the pytroll development, please let us know at the mailing list (pytroll@googlegroups.com) or chat with us directly on the pytroll slack: https://pytrollslackin.herokuapp.com/. We plan to have two pytroll weeks (usually 4-5 days of dedicated programming) each year. Usually we will identifiy a few specific topics that we think needs special attention.

Summary achievements

  • Extending the user community: Several new users have become more familiar with Pytroll and started contributing.
  • Testing: A number of bugs and user inconveniences were identified, and some have been solved already.
  • Enhancements to Pyresample:
    • Now Pyresample allows to attach a weight to the gaussian reprojection method. This is convenient when e.g. gridding several swath products into a level 2.5/3 product (Climate applications).
  • MIPP enhancements and user documentation: MIPP allows XRIT decompression on the fly, and MIPP documentation slightly improved.
  • Three new projects initiated:
    • Pydecorate to add logos, text, color bars and stuff to images
    • Trollimage - an enhancement of the image.py module in mpop including some color enhancements. Will deprecate image.py in mpop
    • Trollduction - A modular batch production framework for Pytroll
  • netCDF reader for SSM/I
  • Trollcast testing, for data exchange between SMHI and FMI - resolution is pending (time outs)
  • Designing and developing the FMI Pytroll based polar production system. Probably resulting in a general concept that can be useful to other users
  • Looking at how to enable web based batch production monitoring with Pytroll. Could e.g. be used for an easy and quick access to Pytroll products for in-house R&D
  • Initiated an overhaul and check of the EUMETSAT recipe RGBs in Pytroll and how they compare and deviate with the official ones. Done in collaboration with the Romanian Met Service.
  • Colorizing Pytroll images (using the new trollimage component) - ‘’sandwich’’ product. Color enhanced imagery is commonly used in forecast offices, e.g. IR imagery with cold temperatures enhanced using a color palette.

Workshop 2012

The first open Pytroll workshop was held in Norrköping, Sweden, end of November, 2012. Nine programmers or satellite experts from Holland, Finland, Romania and EUMETSAT joined up with the pytroll teams at DMI and SMHI, to get more acquainted with the pytroll tools and how it can be used in their local environments for satellite data production.
