&lt;p&gt;This presentation provides an update on the ESA radar altimetry processing services portfolio, known as SARvatore, for the exploitation of CryoSat-2 (CS-2) and Sentinel-3 (S-3) data from L1A (FBR) data products up to SAR/SARin L2 geophysical data products. The following on-line &amp; on-demand services compose the portfolio, now hosted in the ESA Altimetry Virtual Lab at the EarthConsole&amp;#174; (https://earthconsole.eu):&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;The ESA-ESRIN SARvatore (SAR Versatile Altimetric Toolkit for Research &amp; Exploitation) for CS-2 and S-3 services. These processor prototypes allow the users to customize the processing at L1b &amp; L2 by setting a list of configurable options, including those not available in the operational processing chains (e.g., SAMOSA+ and ALES+ SAR retrackers).&lt;/li&gt;
&lt;li&gt;The TUDaBo SAR-RDSAR (TU Darmstadt &amp;#8211; U Bonn SAR-Reduced SAR) for CS-2 and S-3 service. It allows users to generate reduced SAR, unfocused SAR &amp; LRMC data. Several configurable L1b &amp; L2 processing options and retrackers (BMLE3, SINC2, TALES, SINCS, SINCS OV) are available.&lt;/li&gt;
&lt;li&gt;The TU M&amp;#252;nchen ALES+ SAR for CS-2 and S-3 service. It allows users to process L1b data applying the empirical ALES+ SAR subwaveform retracker, including a dedicated SSB solution.&lt;/li&gt;
&lt;li&gt;The Aresys FF-SAR (Fully-Focused SAR) for CS-2 &amp; S-3 service. It provides the capability to produce L1b products with several configurable options and with the possibility of appending the ALES+ FFSAR output to the L1b products. In the future, the service will be extended to process Sentinel-6 data.&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;The following new services will be made available: the CLS SMAP S-3 FF-SAR processor (s-3-smap, http://doi.org/10.5270/esa-cnes.sentinel-3.smap) and the ESA-ESTEC/isardSAT L1 Sentinel-6 Ground Prototype Processor.&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160; &amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;/p&gt;
&lt;p&gt;All output data products are generated in standard netCDF format and are therefore also compatible with the multi-mission &amp;#8220;Broadview Radar Altimetry Toolbox&amp;#8221; (BRAT, http://www.altimetry.info).&lt;/p&gt;
&lt;p&gt;The Altimetry Virtual Lab is a community space for simplified processing services and knowledge-sharing, hosted on the EarthConsole&amp;#174;, a powerful EO data processing platform now on the ESA Network of Resources. This enables SARvatore Services to remain open for worldwide scientific applications, including for R&amp;D studies on the retrieval of radar altimetry measured variables contributing to Inland Water monitoring (write to altimetry.info@esa.int for further information).&lt;/p&gt;
