L Band continuation workshop update

Category : Non classé

Just a few words to say that the L band continuation workshop is now well over. We are preparing some documents and most notably a white paper. We will also put on this blog a post summarising the main findings…

This last week several of us attended also the ESA/ECMWF workshop at ECMWF, complementing usefully the findings of the previous week.

So stay tuned!

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!

My (big) mistake wrt LEWIS

Category : Cal/Val, Data, ground measurements

I would like to complement a statement I made on several posts which is inaccurate!

I said on several occasions that LEWIS had been designed by F Lemaitre from ONERA when he actually designed the receiver etc but not the horn which was designed by CNES (M Dejus). I may even add that the design of the horn inspired the design of EMIRAD horn probably and, moreover, was used directly for CAROLS and MARMOTTE2.

This being corrected, I am glad to add hat LEWIS, in the Alps, is still running strong!
