Jason-2

Jason-2 NRT operation

The Jason2 satellite ( http://smsc.cnes.fr/JASON2/) provides data within 2-3 Days of measurement in the form of IGDR. These data are downloaded and measurements made. The current global masks used to select locations are shown in the combined plot below.
In the above image the possible NRT locations for EnviSat are shown in Red and the NRT locations for Jason-2 are shown in Cyan.

Please be aware that, because this is a new satellite, the Jason1 mask of good quality crossings has been used for this first retrieval of Jason2 river and lake heights; this is shown above in cyan. The performance of Jason2 will now be assessed over many more river and lake crossings; as soon as more targets are confirmed as stable, these will be added, so that over the next few months it is anticipated that significantly more targets will be available from the satellite in Near-Real-Time.
An example of a combined timeseries using the new processor is shown below over the Orinocco River. The historical data provdied by both Jason-1 and EnviSat show very good agreement with the Jason-2 data carrying on the same trend where the historical data ends.
