See Africa Breathing!

Simon Gascoin from CESBIO just sent me this animation he made using CATDS SMOS L3 SM over Africa

SMOS MONTHLY SM Fields over Africa (click to activate)

It is fascinating to see not only the pulsating effect of ITCZ over Africa, but also its counterpart in South Africa, the Euphrates  or the rainy seasons over the Maghreb, the internal Niger delta or the Okavango and many more … Enjoy

New salinity products are available at CATDS!

Category : CATDS, L3, L4, Ocean

Dear CATDS user,

New salinity products are available at CATDS. A new correction for systematic errors (land-sea and seasonal-latitudinal ) has been implemented in CATDS CPDC and in CATDS CEC LOCEAN.

Concerning CATDS CPDC, a RE05 reprocessing of ocean salinity is available from January 2010 to March 2017; the operational processing has been updated accordingly. Binned maps at usual spatial and temporal resolution are available. The SMOS SSS corrected for systematic errors are in MIR_CSQ3 files; non corrected SMOS SSS remain available in MIR_CSF3 files. The corrected product is limited to 45N-47S, the correction remaining uncertain at higher latitudes. A new ATBD is available at http://www.catds.fr/Resources/Documentation.
You can download this product from the usual ftp site : ftp://ext-catds-cpdc:catds2010@ftp.ifremer.fr/Ocean_products/

Concerning CATDS CEC-LOCEAN, 9-day and 18-day products sampled at 25km resolution are provided every 4 days. They cover all latitudes from January 2010 to December 2016 (see further description in the documentation at http://www.catds.fr/Products/Available-products-from-CEC-OS/L3-Debiased-Locean-v2).
A validation of these products has been presented at EGU (see poster at http://www.catds.fr/Resources/Documentation).
You can download this product from the usual ftp site : ftp://ext-catds-cecos-locean:catds2010@ftp.ifremer.fr/Ocean_products/

SMOS research products for the Cryosphere in Antarctica

Category : L3, L4

The aim of the CryoSMOS project, funded by the European Space Agency (ESA) and led by IFAC (Florence, Italy), is to evaluate the ability of SMOS observations to retrieve glaciological parameters or to monitor climatic processes in Antarctica. The study focused on some broad areas of the continent having specific physical characteristics: the Antarctic Plateau, the ice-shelves and the coastal region. Four SMOS derived research products have been developed:

1) Estimation of the internal ice-sheet temperature

Contact : Giovanni Macelloni, g.macelloni@ifac.cnr.it – IFAC, Florence, Italy

2) Estimation of ice thickness

Contact : Niels Skou, ns@space.dtu.dk,DTU, ns@space.dtu.dk – Technical University of Denmark – Denmark

3) Indicator of the origin of ice-shelves variability;

Contact : Lars Kaleschke, lars.kaleschke@uni-hamburg.de, UHAM – University of Hamburg, Germany

4) Surface melting occurrence

Contact : Ghislain Picard, ghislain.picard@univ-grenoble-alpes.fr,IGE – Institut des Geosciences de l’Environnement – Grenoble, France

The data are available from the CATDS and can be found here (free)

Information regarding these products can be found here

More information is available there

Two examples are shown in the figures below. The top most represents the temperature of the ice packs at a depth of 500m. The lower one gives the number of days of melt in 2010/2011.

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.
Enjoy!
