Description
This
amendment presents a new program element in ROSES-2018. NASA is
seeking ways to provide or develop, if needed, in situ instruments,
systems, and approaches for the post-launch vicarious calibration of the
Plankton, Aerosol, Cloud, Ocean Ecosystem (PACE; https://oceancolor.gsfc.nasa.gov)
Ocean Color Instrument (OCI). Ocean color "vicarious" calibration refers to a
final bias adjustment to the calibrated, spectral, top-of-atmosphere radiances
observed by an ocean color instrument. Proposals must consider the PACE
Vicarious Calibration Plan (https://pace.oceansciences.org/documents.htm).
To
produce a time series of spectral data of sufficient quality for ocean color
research, the ocean color sensor must meet stringent calibration and validation
data requirements for performance, uncertainties in the retrievals, and
stability over time. The NASA PACE mission’s ocean color science applications
require highly accurate spectral remote sensing reflectances (Rrs(λ) and sr-1).
Maintaining sufficient accuracy over the lifetime of the mission requires a
robust system vicarious calibration (SVC) program that complements the onboard
calibration devices and enables routine verification and performance assessment
of the ocean color instrument calibration while on orbit. Highly accurate in
situ measurements of Rrs(λ) will provide the
principal source of surface truth for operational
SVC.
