IPF1 vN1.1

First official release of the NRT IPFs. In order to enable the generation of NRT SAR and SARIn products in near real time (2-3 hours after acquisition), the NRT chain was separated from the existing Baseline-D IPFs. This allows processing to use the L0 Star Tracker products instead of the Star Tracker ATTREF products without delay.

IPF1 vN1.1

 

Upgrade of the CryoSat Ice Processors to Baseline-D. This is a major SW upgrade and introduces significant evolutions to the processors with respect to Baseline-C. The update of IPF2 includes:

  • New NetCDF format
  • New SAR/ SARIn stack peakiness parameter added
  • Resolution of a number of known data quality anomalies.

For a list of all known remaining IPF anomalies (ARs) following this update, please see the Product Status page.

FDM: 27/05/2019

IPF1 vM3.0

Minor update of the Baseline-C FDM processors to update the Explorer Geo Correction v4.4, and allow Baseline-C FDM production to be maintained temporarily in overlap with the Ice Baseline-D processors.

SIR1FDM/4.9

FDM: 04/06/2015

Offline: 07/05/2015

IPF1 vM1.0.2

 

SW version issued to implement improvements to the FDM mode. This update includes:

  • Use of Star tracker L0 files in FDM chain.
  • Introduction of attitude information in the L1B FDM Time Orbit Group.

 

Other operative modes (SAR and SARIn) have not been modified at this stage and the processor versions remain unchanged (see below).

IPF1 vM1.0.1

 

SW version issued following a major IPF upgrade. This SW is used to process all products marked by the new Baseline-C and introduces major evolutions to the processors with respect to Baseline-B. The update of IPF1 includes:

  • Provision of additional attitude information in new product fields;
  • Use of best available attitude information coming from the same Star Tracker selected on-board;
  • L1B product format and content changes; Fix of several ARs from the previous IPF1 Vk2.1;
  • Updated configuration parameters in the PCONF, IPFDB and IPF Task Tables.

 

* L1 LRM, SAR, & SARIn data from validity 22/02/2015 to 01/04/2015 is a hybrid Baseline-C using the old Baseline-B orbit model.
