Next meeting and scoping studies
First of all, the next meeting of the stakeholder group will be Monday 6th July
at Harwell. We'll send out the agenda and further particulars nearer the time - for now, just bookmark the date!
The group has received some funding from UKSA for a short-term scoping
study on the implementation of the seamless supply chain, being led by
CEDA and Telespazio Vega.
The first part of the work will look at challenges and opportunities
around the operationalisation of currently existing climate data products. The
initial case studies will be complete at the end of June, so will be
able to report to the wider stakeholder group at the
July meeting. In the first instance, four case studies have been
selected - details below.
Don Grainger, Oxford:
operational implementation of the ‘ORAC’ climate data set derived from the SLSTR sensor on Sentinel 3
The Optimal-Retrieval of Aerosol and Cloud (ORAC) code is a generic
algorithm that estimates aerosol, cloud and surface properties from
space-based imager data. It has been used on measurements by the AVHRR,
MODIS, ATSR and SEVIRI instruments
Barry Latter, RAL:
Retrieved ozone and methane volume mixing ratios on a set of
pressure/height levels spanning the troposphere and stratosphere and
associated a priori profiles, error covariance matrices, averaging
kernels, co-retrieved variables, quality indicators and auxiliary
data used in the retrieval.
RAL-RSG (NCEO) produces these GOME-2 and IASI products from MetOps-A and
–B. The schemes have recently been transferred to JASMIN-CEMS, with
support from the CEDA/JASMIN-CEMS team.
It is proposed through EO4CDS to adapt and extend production to Sentinel-5P and Suomi-NPP CrIS.
Suomi-NPP is in orbit and Sentinel-5P launch due early 2016.
Darren Ghent, Leicester:
• Land and Ice Surface Temperature (LST + IST) record from ATSR-2 and AATSR (and eventually SLSTR) instruments
o Product consists of both Level-2 swath data and Level-3 daily / monthly LST & IST intercalibrated between instruments
o Product contains LST &IST data, total uncertainty, full
breakdown of uncertainty budget, quality control flags, cloud detection
flags, geolocation and viewing geometry information on a pixel-by-pixel
o Auxiliary data utilised in the LST & IST retrieval algorithm are included in the output product
Chris Merchant, Reading:
Sea Surface Temperature Climate Change Initiative: Advanced Very High
Resolution Radiometer level-2 (ESA SST CCI AVHRR L2P) and Sea Surface
Temperature Climate Change Initiative: Analysis (ESA SST CCI Analysis)
Contains global sea surface temperature with uncertainty
characterisation. Proposal is to develop running of Metop AVHRRs
specifically in short delay mode.
