IMOS Remote Sensing Cal/Val

• Twin goals:• Local algorithm and product development• Contribute to global databases and algorithms

• 3 main activities• SST, Helen Beggs@BoM (Presentation by Chris Griffin today)• SSH, Christopher Watson@UTAS• OC, Thomas Schroeder@CSIRO

1. Facility runs only Southern Hemisphere cal/val for SSH

2. Direct feed back to global mission science team making ongoing contribution to the NASA/CNES/ NOAA/EUMETSAT “Jason-class” missions. Contribution at the mission science team level continues to be mutually beneficial.

3. Critical component of future mission design

4. Improves performance of previous missions via retrospective improvements to processing.

5. Jason-3 (was March 2015, but now slightly delayed)

6. Prepare for first of the Sentinel-3 missions:• Plan submitted to the S-3 validation team. • Expanded collaboration with French for S-3

7. Paper at Nature Climate Change revising global mean sea level change over satellite era – crux of which is improved cal/val

OC3 – Aust. bio-optical data base + satellite products• Continued acquisition of bio-optical data from the Australian research

community into the IMOS bio-optical data base and data provision to NASA (SeaBASS) and ESA (Mermaid) as well as ESA’s Ocean Colour Climate Change Initiative (OC-CCI).

Data updates to SeaBASS (Jan-June 2014)

• Locally (NCI) processed whole-of-mission data archives for SeaWIFS, MODIS (with TERN) and VIIRS for use in matchup analysis.

• Aust. MERIS archive also available. • Matchup paper for Global Chl-a alg

submitted.

Sentinel-3 Ocean Colour Cal/Val support

• Joint S3 Cal/Val proposal (CUT, CDU and CSIRO) accepted by ESA/EUMETSAT to support Ocean Colour product validation in the Australian region.

• S3 now to be launched 2nd half of 2015.

• ESA/EUMETSAT acknowledge AERONET-OC as main validation data source for S3.

• 2020 Horizon as external funding source to support IMOS infra-structure very unlikely. Survey outcome on funding priorities (that went to industry) revealed:

Priority for in-situ observations is low and for cal/val very low!
