SMOS retrieves salinity closer to the coast line From J Boutin, and colleagues from LOCEAN Salinity observing satellites have the potential to monitor river fresh-water plumes mesoscale spatio-temporal variations better than any other observing system. In the case of the SMOS mission, this capacity was hampered due to the contamination of SMOS data processing by strong land-sea emissivity contrasts. With...

SMOS: A new tool to monitor the carbon budget of vegetation:... How do the vegetation carbon stocks change at the continental scale? What are the drivers of these changes? These are central questions for the sciences of Climate and for the application of international agreements on climate. A study coordinated by the University of Copenhagen1 has developed a new approach to investigate this issue. In collaboration with scientific...

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.

Caption: ELBARA in Davos-Laret: before winter (the wire mesh is visible on the ground) and when snow is present

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!

Breaking news –> SMOS new LEVEL 2 SM Version in ready!

Category : L2

Dear All

The long awaited SMOS V650 is now ready for release and thus for you to use!

We (ESA and ESLs) have prepared it  tested it, run the reprocessing from beginning to now, and the operational processor is no ready to produce it giving you access to the whole data set!

The main features of the new versions are described in the release note made available with the new distribution. It capitalises as usual on the progresses made at level 1, but the most salient features are

  • the replacement of ECOCLIMAP by IGBP which enables to have i) an up to date land use map and ii) to be aligned with SMAP and Aquarius,
  • the use of CdF matching in mixed forest nominal pixels and much more accurate and
  • relevant DQX and Chi2
  • Finally the way the current files are updated is also improved.

As  a consequence the new version is « wetter » at high latitudes and around forested areas (with also higher VODs), more retrievals are successful. In terms of metrics with respect to our usual sparse and dense networks, both correlation coefficients and RMSE  are improved but also thereis no bias at all while the SDTE remains the same.

V651-SM

Difference (V650-V620) of averaged soil moisture (4 months per year January; April, July and October) during 7 years.

V650-Tau

Difference (V650-V620) of averaged vegetation opacity (4 months per year January; April, July and October) during 7 years.

Data and documentation available at the usual ESA / Array addresses

Note that the SM NRT are being updated. CATDS L3 will also be updated, but after we have corrected an issue with L3 temporal approach algorithm.

Have fun!
