Altimetry & Oceanography with the BRAT Toolbox - Part 2

This webinar edition is divided into two parts.

We suggest you to repeat the part 1 of this webinar. You can find the recorded version of part 1 here.

Part 1 (held on 18 July 2019) - An introduction on radar altimetry will discuss the Low Resolution Mode (LRM) and Synthetic Aperture Radar (SAR) processing schemes in combination with the analytical and empirical retracking strategies used to produce the typical estimates included in altimetry products. In BRAT, altimetry estimates in the coastal zone will be discussed underlining the importance of correctly applying the geophysical corrections. 

Part 2 - This webinar will be oriented to oceanography. The 27-days repeat cycle of Sentinel-3 will be used to assess the impact of a typhoon event on altimetry estimates. The possibility of generating monthly sea level anomaly (SLA) maps with BRAT will be also discussed as well as the capability of the toolbox to calculate geostrophic currents and the current speed.

During this webinar, you will be introduced to Sentinel-3 SRAL altimetry data and learn how to process the data using the ESA/CNES Broadview Radar Altimetry Toolbox (BRAT). 

Please note the duration of this webinar is of 1 hour 30 minutes + 20 minutes for Q&A


Since the 1970s altimeters contribute to monitor the health of planet Earth providing measurements on sea level and supporting oceanographic studies. In particular, the monitoring of sea level rise at the coast is of cardinal importance and altimeters can contribute to evaluate the threat at regional scale, especially in areas of the world that are poorly instrumented.

In the recent years, the progress made in signal processing schemes brought a significant improvement in the resolution of altimetry sensors. As a result, altimeters on board missions like Sentinel-3 are capable of providing usable estimates not only in the open ocean but also in the coastal zone, over icy regions and over rivers & lakes. 

The Sentinel-3 mission is composed of a constellation of 4 satellites (Sentinel-3A, B,C,D). Sentinel-3A & Sentinel-3B have been successfully launched in 2016 & 2018, respectively. The main objective of the Sentinel-3 mission is to measure sea surface topography, sea and land surface temperature, and ocean and land surface colour with high accuracy and reliability to support ocean forecasting systems, environmental monitoring and climate monitoring.
