First GDR meeting in Paris, October 9, 2008

1. For the first meeting of this group, we selected a subject that:
   

2. is of interest to different aspects of atmospheric studies (atmospheric sounding of temperature, water vapor, and trace gases, cloud/rain retrieval, planetary atmospheres)
   

3. is the object of  several satellite mission projects
   

4. is technologically challenging
   

5. 
   

6. More than 30 participants from 18 different labs attended this one-day meeting (see the participant list attached). In the millimeter and sub-millimeter domains, long-term collaborations have been set up between different French labs and the European community, both on scientific and technical aspects. Experts from other countries have been invited to present their work and views to this meeting and several European labs were represented (CSIC, Spain; RAL, UK; University of Lulea, Sweden; University of Chalmers, Sweden).

8. The program of the meeting included several presentations and a discussion, the objective being to favor exchanges among participants. The invited talks tended to cover the different aspects of the millimeter and sub-millimeter domains. The report of the meeting is downloadable below. It gives a short summary of each presentation. The participant list is included at the end of the report . The full presentations are available on the page “Documents” .

Fifth GdR Workshop on “Ice clouds observed by microwaves”, Observatoire de Paris, 17 April, 2014

1. The 5th GdR Workshop was organised at Observatoire de Paris, on April 17, 2014, about  remote sensing of ice clouds from satellites. It focused on the microwave observations, both passive and active, but the synergy with the visible and infrared measurements were also discussed. The workshop was attended by more than 25 participants. 11 oral presentations were given, followed by discussions between the participants. Minutes of the meeting are available below, in French and in English. The presentations are available for download in the Documents section of this website.
   

The 3rd International Sub-Millimeter Airborne Radiometer (ISMAR) workshop , Observatoire de Paris, 28-30 September, 2015

1. The 3rd International Sub-Millimeter Airborne Radiometer (ISMAR) workshop was organized by LERMA at Observatory of Paris on 28-30 September 2015. The objectives of the workshop were :
   

2. -  To provide to the European community working on sub-millimeter wave radiometry a status of the instrument itself, on its upcoming technical developments, on future ISMAR-dedicated field campaigns and on possible collaboration with other international measurement campaigns
   
   

3. -  To discuss on the ISMAR observations collected during its first research flights,
   
   

4. -  To present preliminary results on the analysis of the first ISMAR data,
   
   

5. -  To discuss on the way forward for the preparation of Ice Cloud Imager (ICI) using ISMAR.
   The workshop consisted in a series of technical and scientific presentations, all related to ISMAR and its potential use in specific field campaigns. Activities related to HALO Microwave Pack (HAMP) were also presented. The list of participants is given in Annex A. The program is available in Annex B.
