  1. CLARREO SDT Meeting Introduction Bruce Wielicki Science Team Lead National Institute of Aerospace Hampton, VA November 14-16, 2017

  2. Introduction • Meeting Goals: • CLARREO Science Results (Tuesday/Wed) • Status of CLARREO Pathfinder Mission (Wed PM) • Discussions of the Future Science Landscape (Wed PM) • New Administration and NASA Budget: • Bridenstine passed Senate committee, total senate vote is next. • NASA Senate and House FY18 budgets yet to be reconciled and passed • Continuing Resolution through December 8, 2017 • Current missions continue as before (including CLARREO Pathfinder and Pre-Formulation activities) • Both Pathfinder and Pre-formulation have funding through March, 2018 • Funding beyond that depends on final Congressional budgets (or extended continuing resolution) as well as Decadal Survey report Keep focus and working on the long term CLARREO goals

  3. CLARREO Pathfinder on ISS (early 2022) CLARREO Pathfinder Continues in Phase A in 2017, first half of FY18

  4. CLARREO Pathfinder Mission Summary • Demonstrate CLARREO calibration accuracy for the reflected solar spectrometer on International Space Station • Nominal launch is early 2022, nominal operations 1 year to start but will request longer when reach critical design review successfully. • Infrared spectrometer did not fit in the budget: pursuing other options to add an infrared Pathfinder. • Class D low cost mission • Instrument design life 1 year at 85% probability, ~ 50% of achieving 4 yrs • Demonstrate CLARREO level SI traceability in orbit (0.3%, k=1) • Demonstrate CLARREO Reference Intercalibration for VIIRS and CERES instruments (0.3%, k=1) • Take intercalibration observations for additional sensors (LEO, GEO) but Pathfinder budget only covers L0 processing for these orbit crossings • If demonstrate success, then request funding to process full data stream and additional instrument intercalibration events, as well as nadir spectral benchmarking observations.

  5. CLARREO Pathfinder on ISS • Level 1 (radiance/reflectance) and Level 4 (orbit crossing intercalibration) observations will be publicly available. No level 2 or 3 products in current budget. • Lessons learned from CLARREO Pathfinder will benefit a future CLARREO mission • Reduced risk • Demonstration of higher accuracy calibration approaches • Prove that high accuracy SI-traceability can be transferred to orbit • Show that high accuracy intercalibration is achievable • CLARREO Pathfinder will demonstrate highest accuracy radiance and reflectance measurements from orbit • First on-orbit SI-traceable reflectance with uncertainty <0.3% (k=1) • Lessons learned from CLARREO Pathfinder will produce benefits across many NASA Earth Science Missions and International Missions • Improved laboratory calibration approaches • Development and testing of innovative on-orbit SI-traceable methods • Transfer calibration to sensors in operation at time of CLARREO Pathfinder • Improved lunar irradiance standard CLARREO Pathfinder will improve accuracy across Earth Sciences

  6. CLARREO Pathfinder on ISS: Milestones • System Requirements Review (SRR/MDR) successfully passed July, 2017 • Key Decision Point B (start of phase B) TBD until budgets for FY18 are finalized. • LASP instrument contract delayed until budget clarifies. If go ahead from HQ is given by December 1, 2017, then contract expected end of March, 2018. Slips beyond then may be day for day. Early 2022 launch. • More Detailed information on Pathfinder later in the SDT meeting (Wednesday afternoon) CLARREO Pathfinder will improve accuracy across Earth Sciences

  7. CLARREO Pre-Formulation Summary • Continued funding through March 2018 at FY17 levels. • Because Pathfinder is focused on RS instrument demonstration, pre-formulation is now focused on IR instrument design and risk reduction. • Langley has been working on instrument component prototyping and design • UW has been working on risk reduction for QCL laser and blackbody paint. • Continuing climate model OSSE studies which will be reported on during the meeting. • Using multiple climate models with low, typical, and high climate sensitivity • Modifying OSSE framework to use PCRTM reflected solar code (Xu Liu et al.) to greatly speed up future OSSE runs and allow larger model ensembles (CMIP models)

  8. CERES FM-6 Launch on JPSS-1? • Currently planned for Wednesday, Nov 14 at 4:30am EST
