RADCALNET building blocks: 2 yr pilot project • Initially 3 instrumented sites will provide data to RADCALNET:
Baotou (China) La Crau (France) Railroad Valley Playa (US)
+ New ESA/CNES site to be selected and equipped over next 12 months - Global search based on methods defined by CNES study
• Site owners to provide locally QA/QC data
• ESA project to develop protocols, means to collect, distribute QA/QC and harmonise data from sites to users (prototype service)
• NASA to process all in-situ data leading to hyperspectral TOA radiances (30 minutes blocks)
• NPL to provide Traceability to site measurements, facilitate harmonisation, uncertainty analysis of network results i.e. QA4EO
‘Service’ tested with Landsat 8, Spot 5, Proba V, DMCii, + others TBC also ready for Sent 2 - include comparisons of methods to - link in-situ to satellite - satellite to satellite - Network to satellite
SUMMARY of Current actions
• Detailed Technical project plan & potential ‘network members handbook’ in draft – next meeting in Feb @ NPL
• WG meetings co-located in conjunction with IVOS
• During 2 yr pilot phase outputs contained to project team
• If pilot successful look towards an ‘operational system’ in future – more sensors, more sites!

Current status • Nearing final selection (weeks timescale)
• Established a number of sites (varying level of adequacy) across globe
priority locations: • Australia • Morocco • Saudi Arabia • Namibia • Chile
• Established and had discussions with local contacts
• Probable Favourite for European site at present – Chile
• Encourage establishment of other future RADCALNET sites by local
teams, with guidance from Radcalnet WG.
