I'm on the steering committee of this workshop because I have had so many excellent collaborations that have stretched my thinking as a metrologist and brought new ideas to the Earth observation communities I've worked with. #FIDUCEO @qa4eoCalVal #RadCalNet @ESA_EO
Great to see the next generation of metrologists getting involved!
And a brilliant artistic rendering of #RadCalNet's work πππππ°οΈποΈ
During the #RadCalNet WG meeting this evening, one of my teammates was joined by her young daughter who listened carefully and drew this summary slide with the sun, Earth, a spectrum, lots of satellites and at the top the data - a graph of the site comparisons! Isnβt it great?!

Are you a #RadCalNet data user? We're organizing a RadCalNet users workshop on 9 June- contact me for details. RadCalNet is a network of instrumented ground sites with SI-traceable calibrations for satellite vicarious calval. See: https://t.co/s4Pvu8yP8V - new users welcome too!

7:30am start worth it for an interesting meeting with the Chinese colleagues running the Baotou sites and @ESA_EO about #RadCalNet. Exciting developments - the sandy site is approved (data will be available soon) and extensions to the SWIR are planned. #EOMetrology. @NPL

The paper I collaborated with the Chinese Academy of Sciences on, is published: applying a metrological approach to the Baotou #RadCalNet instrumented reference site for visible and near infrared satellite vicarious cal/val. @MDPIOpenAccess https://t.co/tZCrFtg4Et #EOMetrology
3. Setting up #RadCalNet 2014-now. RadCalNet is a @CEOSdotORG network of instrumented sites providing SI-traceable top-of-atmosphere nadir reflectance values every 30 minutes for satellite vicarious calibration. https://t.co/s4Pvu8hehn.
Back in March FSF and @NPL headed to @GobabebRSH in #Namibia to conduct some preliminary fieldwork for #RadCalNet and #Hypernets Horizon 2020 satellite calibration sites. Read about everything we got up to here: https://t.co/ai8eocQ6wm #spectroscopy @NCEOscience @NERCscience
A new #RadCalNet site dedicated to validation of surface reflectance in complex landscape. https://t.co/tHlkN271NO
It's our last day in the Namib Desert today, and we've been hard at work all week doing multispectral and hyperspectral surveys of the #hypernet and #radcalnet sites here. We've used #SVC and #ASD spectrometers simultaneously, and our new MAIA S2 multispectral camera! @NPL
Last summer, Emily Mitcheson-Smith, an UG from Southampton Uni spent two months with us as part of the #SEPNet summer placement scheme looking at the uncertainties for off-nadir viewing angles of #RadCalNet. Last week she was one of the winners of the SEPNet poster competition.
#RadCalNet now has a reference paper. RadCalNet provides bottom and top of atmosphere (400 - 2500 nm) reflectance data every 30 minutes at 4 sites across the world for satellite calval. https://t.co/vOy868Uo6G @RemoteSens_MDPI #EOMetrology @NPL @ESA_EO @NASAClimate
