-  - Raman scattering - WP3100, status: ongoing\\ The code is partly implemented, albedo is not implemented jet, results will be compared to literature+  - Raman scattering - WP3100, status: ongoing\\ Raman scattering is basically implemented; the spectral signature of the Raman-scattered radiation compares well with exisiting results, the absolute magnitude is not yet correct. After implementation of surface albedo the results will be evaluated by comparison with published results
-  - Polarization in MYSTIC - WP3200, status: ongoing\\ Polarisation for solar range implemented in MYSTIC. CE presented comparisons with //polradtran//. Some progress has made for calculation of optical properties of aspherical particles. If suitable tools are availeble, they will be added to the software package. +  - Polarization in MYSTIC - WP3200, status: ongoing\\ Polarization for solar range implemented in MYSTIC. CE presented comparisons with //polradtran//. Some progress has been made for calculation of optical properties of aspherical particles. If suitable tools are available, they will be added to the software package.\\ An optical properties database for liquid water clouds will be generated using the Mie program (Wiscombe), that is already included in libRadtran
-  - Extension of surface properties - WP3300, status ongoing\\ The code of Mishenko, which simulates polarised BRDFs, is suitable for implementation in libRadtran. +  - Extension of surface properties - WP3300, status ongoing\\ The code of Mishchenko which simulates polarized BRDFs is suitable for implementation in libRadtran. 
-  - Representation of aerosols -- WP3400, status: closed\\ Optical properties of OPAC aerosols were precalculated. Different kind of aerosols can be mixed during the libRadtran simulation+  - Representation of aerosols -- WP3400, status: closed\\ Optical properties of OPAC aerosols were implemented: Tables of optical properties were pre-calculated and a user-friendly interface has been built to directly define mixtures of aerosol types in the uvspec input file. The implementation is already included in the 2008 Christmas release of libRadtran.  
-  - Development of graphical tools - WP3510, status onging\\ Some preparing work was done, including //data_files_path// environment variable, syntax checking of the input. A demonstration version will be presented next meeting. +  - Development of graphical tools - WP3510, status onging\\ Some preparatory work was done, including restructuring the directory structure of libRadtran; the possibility to install libRadtran system-wide using "make install";  the //LIBRADTRAN_DATA_FILES// environment variable; and syntax checking of the input. A demonstration version will be presented at the next meeting. 
-  - Include I/O-functions for //netcdf// data format - WP3520, status closed\\ Several input and output options are implemented. UH presents some results at the midtime meeting+  - Include I/O-functions for //netcdf// data format - WP3520, status closed\\ Several input and output options are implemented.  
-  - Fix DISORT instability - WP3540, status ongoing\\ An instability caused by the intensity correction is under investigation+  - Fix DISORT instability - WP3540, status ongoing\\ Some work has been done on the intensity correction of disort2.  
-  - Cleaning/restructuring of code - WP3550, status ongoing\\ The consistent treatment of ice cloud optical properties was implemented. +  - Cleaning/restructuring of code - WP3550, status ongoing\\ The consistent treatment of ice cloud optical properties was implemented which greatly facilitates the definition of ice clouds for the user; all optical property parameterizations (Fu, Yang, Key, Baum, ...) use now the same definition of optical thickness and effective radius (before, Fu used e.g. a different definition as Yang in the orginal paper and we stuck as closely as possible to the original paper) 
-  - Miscellaneous\\ For //line-by-line// simulations, a python interphase was developed. This needs more testing in the UV/VIS.\\ The //webpage// of libRadtran was redesigned. Now it offers a user area and a basic usage instruction additionally. MB suggests to add a user forum as well.+  - Miscellaneous\\ For //line-by-line// simulations, a python interphase to ARTS was developed. This needs more testing in the UV/VIS.\\ The //webpage// of libRadtran was redesigned. Now it offers a user area and a basic usage instruction additionally. MB suggests to add a user forum as well.
A demonstration version of libRadtran will be installed by MB with telephone assistance. A demonstration version of libRadtran will be installed by MB with telephone assistance.
-The ESASLight website has been approved by MB as a useful tool.  +== Review of action items ==
-== Progress Meeting 4 == +//Actions from PM2// 
-The midtime review meeting will take place at the **1st of April at ESTEC**. This meeting will be used to inform people from ESA about ESAs light. There will be a 30 min presentation of the whole project, its objectives and the recent developments, and another presentation of 15-30 min about the applications of libRadtran.+
