  1. Post-launch calibration/validation at several scalesJoel McCorkel, Kurt Thome, Bruce Cook

  2. Joel McCorkel – NASA GSFC NASA projects • CLARREO Reflected Solar Calibration Demonstration System • Goddard IRAD for SIRCUS development • Science Task Group: Multi-mission, Multi-discipline working group approach to calibration • JPSS Science/Calibration, VIIRS Landsat Science Team - Launch Meeting

  3. Recent CLARREO-related activities FY13: Continue development of SOLARIS CDS • Solar/Lunar for Absolute Reflectance Imaging Spectroradiometer Calibration Demonstration System • Demonstrate 1% calibration in select spectral region • SIRCUS-based calibration error budget • Absolute reflectance accuracy report • Create field-portable version of SOLARIS (Suitcase SOLARIS) • Round robin comparison with University of Arizona transfer radiometer (known for use with MODIS and Landsat 8/OLI) • Field deployment for aircraft and satellite sensor intercalibration Suitcase SOLARIS Silicon trap radiometer Landsat Science Team - Launch Meeting

  4. G-LiHT Goddard’s Lidar, Hyperspectral, and Thermal Airborne Imaging System • PI Bruce Cook • Lidar • 1550 nm • waveform • 60° scan • 7/m3 pulse density • VNIR imaging spectrometer • 0.4–1.0 μm • 1.5-nm sampling • 1-m spatial sampling • Thermal imager • Non-cooled microbolometer • 8–14 μm broadband • 0.45-m spatial sampling • 335-m AGL, 110 kt Landsat Science Team - Launch Meeting

  5. Scales of measurement • G-LiHT (B. Cook) • Lidar • Hyperspectral • Thermal VIIRS, MODIS Landsat 7 and 8 tandem orbit • CLARREO-SOLARIS • Imaging spectroradiometer • High-accuracy point measurement • Reflectance characterization • Site-based measurement • Traceable via reflectance standard Landsat Science Team - Launch Meeting

  6. G-LiHT targets for underflights? Landsat 7 and 8 tandem paths in western US • Mar 29 path 38 • Mar 30 path 45 • Mar 31 path 35 Mar 31 Mar 30 Mar 29 Aircraft/G-LiHT integration NEON-D16 Wind River HJ Andrews Experimental Forest Lake Tahoe Railroad Valley Vineyard tower NEON-D17 San Joaquin/pre-HyspIRI activities Ivanpah Playa Kingsburg tower Lordsburg Playa Algodones Dunes Landsat Science Team - Launch Meeting

  7. Scales of product R. Kao et al, 2012 R. Kao et al, 2012 Landsat biophysical products will be about one order of magnitude in between MODIS and NEON-airborne, spatially and temporally Landsat Science Team - Launch Meeting
