Amendment 31: New Opportunity Solar Irradiance Science Team Added to ROSES-2020.
The primary purpose of A.49 Solar Irradiance Science Team (SIST) is to support the development of consistent multi-instrument/multi-platform space-based data sets of both total and spectrally resolved solar irradiance. The data sets should be useful as input to global models (e.g., general circulation models, atmospheric chemistry/transport models) and data assimilation systems, so that the effects of variations in solar output can be properly represented and their impacts on the Earth system investigated. The efforts carried out in this area will be expected to involve components such as:
• Rigorously accounting for drifts in instrument operation over their respective lifetimes,
• Determining calibration offsets that can be applied to one or more data sets to create a consistent data record,
• Reprocessing data sets for previously operating satellites using newly obtained calibration information
• Analyzing and/or interpreting laboratory or other (balloon, rocket, etc.) Calibration data that can be used to recalibrate existing data records,
• Intercomparing total solar irradiance and spectrally resolved solar irradiance observations to describe changes in the relationships between them that may provide a mechanism for establishing relative consistency or inconsistency of different approaches for connecting disparate data sets,
• Comparing solar irradiance data sets with those of solar irradiance proxies, to help define the range of relationships between them and support the inference of longer-term solar irradiance records that can be used to force models as described above, and
• Exploring methods for bridging with minimal impact previous or future gaps in solar irradiance records that can occur with the unexpected loss of an instrument or failure to launch subsequent instruments in a timely manner.
ROSES-2020 Amendment 31 adds a new opportunity: Solar Irradiance Science Team in program element A.49. Notices of intent are requested by August 7, 2020 and proposals are due September 11, 2020.
On or about June 8, 2020, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2020" (NNH20ZDA001N) will be posted on the NASA research opportunity homepage at http://solicitation.nasaprs.com/ROSES2020.
