Minimize CryoSat IPF Processing Baseline: Level-2 Ice Products

Back to CryoSat IPF Baseline

Information on the historic IPF2 baseline for CryoSat Ice Products is provided in the table below.

The current version of IPF2 is listed below, followed by information in the corresponding table providing the:

  • IPF installation date
  • Changes with respect to the last IPF version
  • Various processor versions corresponding to the IPF update

Detailled information concerning the products is available in the latest version of the Product Format Specification document for L2 Ice Processor

Detailed information concerning the main evolutions for the L2 Ice Processor with respect to the last IPF2 is available here.

Current IPF2 installed at Kiruna PDS: vM1.0.4

IPF2 vM1.0.2 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 includes:
  • L2 product format and content changes
  • Refinement of the OGOG and CFI land-ice retrackers (LRM)
  • New retracker for land ice (LRM)
  • New retracker and freeboard activation (SAR)
  • Use of new Arctic MSS (SAR), Antarctica and Greenland DEM (SARIn), updated Slope Model (LRM)
  • Fix of several ARs from the previous IPF2 Vk1.2
  • Updated configuration parameters in the PCONF, IPFDB and IPF Task Tables
*L2 and L2i LRM, SAR, SARIn & GDR data from validity 22/02/2015 to 01/04/2015 is a hybrid Baseline-C, using the old Baseline-B orbit model.
