2017-09-04: New Single Scattering Database (Beta version)

A beta version of a new single scattering database of mainly ice particles that has been calculated using the discrete dipole approximation method (DDA) is now available for download.

2017-03-07: ARTS Workshop 2017

We are pleased to announce a new workshop in the series of "ARTS workshops". You don't need to be an ARTS user or developer to participate, the workshop is open for all with an interest in atmospheric radiative transfer. There is normally a strong focus on microwave to infrared radiative transfer, but also other wavelength regions are of interest.

The place is the same as last time, Kristineberg (about 100 km north of Gothenburg). Time for the actual workshop: September 6-8 (Wednesday morning to Friday lunch). We will arrange transport between Gothenburg and Kristineberg, and it will departure from Gothenburg around 15.00 September 5. That is you need to arrive to Gothenburg not too late Sep 5, and should have possibility to travel back Sep 8.

The general goal of the workshop is as usual, that the ARTS user community (and also people working with other RT models) can meet, get to know each other, solve practical problems, and discuss the further development of the program. As always, we will have only a relatively small number of talks, and instead more time for group work and discussions. The present/planned main development of ARTS is directed towards

  • Faster scattering calculations
  • Running OEM inside ARTS
  • Non-LTE

but the workshop is not restricted to these topics.

If you are interested in participating, then please fill in the pre-registration form in order to allow us plan the program. The deadline for pre-registration is March 31. Since the available space at Kristineberg is limited, we have to limit the meeting to roughly 25 persons. If more persons are interested, it will be first come first served.

Kristineberg is a marine research station. The station offers full board and lodging, but the number of rooms is limited and most workshop participants will need to share double rooms. At the moment there are only three single rooms at hand. If you require a single room indicate this under Comments. Transport to/from Gothenburg is arranged at start/end of workshop. You only pay for room and food at Kristineberg. We can not yet give you en exact price, but it should be in the order of 250 euro.

2016-09-07: Current ARTS development

Although there hasn't been a new stable ARTS release in a while, the ARTS team is very busy working on new features in the development branch. To give you a glimpse of the current development, here is a list of some features we're working on:

  • Line mixing calculations.
  • Consideration of non-LTE effects.
  • Several optimizations have be applied to DOIT, one of ARTS' scattering solvers. This includes an improved conversion algorithm and an optimized pressure grid. More enhancements are still being worked on.
  • Integration of the RT4 polarized model for horizontally oriented particles by Frank Evans into ARTS as an additional scattering solver.
  • Integration of the NWP SAF sea surface model FASTEM into ARTS.
  • ARTS' internal catalog format (ARTSCAT-5) has been improved and now supports storage of various pressure broadening schemes, various line mixing schemes and quantum numbers.
  • Overhaul of the Disort integration.

Once the dust settles and the new features are polished, we hope to release a new stable ARTS version in the near future.
