Announcing the RFI 2019 workshop in Toulouse

Category : Non classé

We have the pleasure to announce that the Radio Astronomy and Remote Sensing communities are again working together in organizing an RFI 2019 Workshop to provide an opportunity for the scientific community affected by Radio Frequency Interference (RFI) to meet, report and discuss recent achievements and developments in instrumentation, methodology, and applications in tackling this problem.
The Call for Papers is attached here. RFI 2019 will take place on September 23-26 2019, in Toulouse, France. The abstract submission deadline is on May 31, 2019. Further derails are available on the workshop website at <>.

Interesting stuff from Davos (Laret) (for once?!)

Category : Data, ground measurements

Davos is well known for some meetings taking place up there. But our Colleagues from WSL and Gamma Remote sensing are carrying out a very interesting experiment as detailed below by Mike and Reza!

Davos-Laret Remote Sensing Field Laboratory: Latest Results and Progress

Reza Naderpour and Mike Schwank

The Davos-Laret Remote Sensing Field Laboratory (Switzerland) was established in October 2016 as the only currently-operating Alpine test site dedicated to the development of novel retrieval approaches for the estimation of snow properties from passive/active microwave remote sensing data.

The second winter campaign started on November 18, 2017 simultaneously with the publication of the first paper based on Winter 2016/17 campaign:

Naderpour, R.; Schwank, M.; Mätzler, C. Davos-Laret Remote Sensing Field Laboratory: 2016/2017 Winter Season L-Band Measurements Data-Processing and Analysis. Remote Sens. 20179, 1185.

Accessible here:

With two more upcoming papers, the research conducted in the Winter 2016/17 campaign has mainly investigated the retrieval of snow liquid water content from L-band radiometry as well as disturbing impacts of snow liquid water on the ground permittivity and snow density retrievals. Additionally, several data processing improvements, including a refined RFI mitigation approach, are suggested which can be of high interest to ELBARA users. See the PDF file for more information on the 2017/18 campaign and close-up details of the campaign practicalities!


New release of L3TB

Category : CATDS, L3

It was noticed by several users that our new RFI filter was overdoing things a bit (actually one of the flags was wrong) leading to a very reduced amount of available brightness temperatures, in our L3TB product (version number 300).

The bug is corrected and the whole data set (L3TB and L3RFI, since 2010) has been reprocessed.

The new products have version number 310.

Changes in SMOS L3 TB

Category : CATDS, L3

Important information…

It was noticed by several users that our new RFI filter was overdoing things a bit (actually one of the flags was wrong) leading to a very reduced amount of available brightness temperatures.

We are working on this issue and already François and Stéphane have patched the bug and tests were carried out at CESBIO before implementation which is underway at CATDS.

The new products will have version number 310

Very soon the operational algorithm will release -less abusely filtered -  L3TB data (with more measurements thus) and we will also reprocess the whole data set (both L3TB and RFI).
