The Pont des Arts or Passerelle des Arts is a pedestrian bridge in Paris
which crosses the Seine River. It links the Institut de France and the
central square (cour carrée) of the palais du Louvre, (which had been
termed the "Palais des Arts" under the First Empire).
2012-02-24: ARTS development moving on to 2.1, stable 2.0 version available in branch.
We would like announce that the development of ARTS in the Subversion trunk is moving on to version 2.1. If you like to stick with the latest stable version, we recommend that you switch to the new 2.0 branch. Head over to the 'Getting ARTS' page to learn how to checkout the latest stable version.
The version numbers of related tools like atmlab and PyARTS have been increased to 2.0 to reflect compatibility with the corresponding ARTS version. Download information is available on the 'Related Tools' page.
Non-subversion users can find all stable packages at http://www.sat.ltu.se/arts/misc/download/stable/2.0/.
2011-09-02: We're pleased to announce the release of ARTS version 2.0!
In comparison to version 1 (by us now denoted as ARTS-1), this ARTS version is a much more sophisticated software (summary below). Most of these features have been in place since years. More lately, we have spent time on the documentation and this is the reason to why we now declare that ARTS has reached version 2 status.
ARTS is a state-of-the-art radiative transfer model for the thermal spectral region:
- The model atmosphere can be 1D, 2D or 3D.
- Spherical geoid and surface are throughout default. For 2D and 3D more complex topography are also possible.
- Radiative transfer can be made for 1–4 Stokes elements. Polarisation effects can thus be fully described.
- Basically no restriction in complexity of surface reflection (but is currently handled only in a simplistic manner).
- For particle single scattering properties, not only the standard assumption of spherical or completely randomly oriented particles, but also the case of horizontally aligned particles is handled.
- Two modules for solving radiative transfer with particle scattering: MC and DOIT. Both modules lack intrinsic approximations, and have been verified by practical retrievals.
- Sensor responses can be incorporated in an efficient manner.
- Concept of agendas and include files for more flexibility in control files.
- Built-in HTTP documentation server.
For an introduction to the new features of ARTS, please have a look at the following JQSRT article:
- ARTS, the atmospheric radiative transfer simulator, Version 2, Eriksson, P., S. A. Buehler, C. P. Davis, C. Emde, and O. Lemke (2011), J. Quant. Spectrosc. Radiat. Transfer, doi:10.1016/j.jqsrt.2011.03.001. http://www.sat.ltu.se/arts/docs/arts-2-0-paper.pdf
We recommend to get the latest source code directly from our Subversion repository. This is the easiest way for you to keep your ARTS version up to date. Instructions on how to get ARTS from Subversion can be found at: http://www.sat.ltu.se/arts/getarts/
If you can't use Subversion, you can also get the latest snapshot of the ARTS source code package at http://www.sat.ltu.se/arts/misc/download/arts2/
