April 2018: Call for abstracts for the "International Review Workshop On Satellite Altimetry Cal/Val Activities and Applications"

Tue, 2018-01-09 03:09
The call for abstracts is now open for the  "International Review Workshop On Satellite Altimetry Cal/Val Activities and Applications".  This International Review is to be held in Chania, Crete, Greece, 23-26 April 2018 and is sponsored by the European Space Agency, EUMETSAT and the IAG/IUGG Commission 2.

The aim is to present the latest research results in the field of satellite altimetry calibration and altimetry applications for monitoring ocean changes and for improving Earth observation in an objective, continuous, homogeneous and reliable manner, free of errors and biases, and tied from one altimetry mission to the next. The intention is to support long-term monitoring of climate changes by understanding better environmental changes on world's oceans, terrestrial surface waters, but also on Arctic and Antarctic polar regions. The final outcome is to establish and promote a scientific roadmap with procedures, protocols, guidelines, and best practices in an open and transparent way to be followed by any international group working on satellite altimetry to attain SI traceability of their measurements, results and data products.

El Niño impacts erosion in the Peruvian Andes

Wed, 2017-12-06 02:11
El Niño and La Niña are the names of climate events occurring in the tropical Pacific Ocean, which are now globally infamous. They characterise a close relationship between the ocean and the atmosphere, in which the main protagonists can have devastating consequences worldwide. A recent study from French-Peruvian researchers published in Nature shows that extreme El Niño events also impact rainfall patterns and erosion in the western Peruvian Andes. More intense and more frequent rainfall events are observed during extreme El Niño events in the Peruvian Andes, especially in the Northern area. Catastrophic floods in Northern Peru and Ecuador are observed. In-situ river measurements and sediment accumulation measurements show greater erosion trends during the 1982-83 and 1997-98 El Niño events. Further information:

[Sentinel-3A] New version of Non-Time-Critical Sentinel-3A L2P products

Fri, 2017-11-17 01:49
These products are processed by the Sentinel-3 L2P/L3 Marine Altimetry Service (CNES/CLS), in the frame of a EUMETSAT contract, funded by the European Union.  The new version 02_00 is disseminated by AVISO+ via ftp or AVISO+ CNES Data Center (see the product sheet). Note that the last cycle produced in version 01_00 has already been delivered (cycle 22). The next cycle 23 will be produced only in version 02_00.  With this new version:
  • the input data are the “spring 2017 reprocessed” version of input NTC L2 products fully detailed in the EUMETSAT S3A STM reprocessing technical note
  • the standards are the same as in 01_00 version
  • new cycles are available (cycles 5 to 11)

Dissemination of incorrect Jason-2 IGDR products (cycles 507 to 512)

Thu, 2017-11-16 02:14
Due to a wrong processing configuration, Jason-2 IGDR cycles 507 to 512 are incorrect (datation bias of over 2ms, same anomaly as for cycles 505-506). These products have been deleted from avisoftp.cnes.fr server and must be discarded. The IGDR processing configuration anomaly has been identified. Jason-2 IGDR reprocessing is ongoing. Nevertheless, these products need validation before any dissemination. We expect to be back to nominal by the middle of next week.  We apologize for the inconvenience

Water Action Day at COP23 : Niger Basin Authority (NBA) collects & disseminates satellite data

Wed, 2017-11-15 02:46
The Niger basin (4.200 km) encompasses 2,2 billions km² with very active phenomena, over nine countries (Benin, Burkina Faso, Cameroun, Ivory Coast, Guinea, Mali, Niger, Nigeria and Chad). An authority to manage the basin was created The region has currently major security problems, leading to difficulties to maintain an in situ network. Satellites thus complement the existing network, and the Niger Basin Authority (NBA) is now disseminating satellite data over the basin. The next step will be to also use altimetry, including SWOT in the future. see http://sath.abn.ne/
