Title: Broadband Radiometry during EarthCARE: An Improved Solar Radiance-to-Flux Conversion
Abstract: Outgoing radiative fluxes at top-of-atmosphere (TOA) are driven by the interaction of clouds, aerosols, and radiation. The upcoming satellite mission EarthCARE aims at an improved understanding of this interaction through a radiative closure assessment based on TOA fluxes. This assessment compares (1) shortwave (SW) and longwave TOA fluxes inferred from an onboard broadband radiometer (BBR) with (2) fluxes from radiative transfer calculations acting on cloud and aerosol properties that were retrieved from onboard active and passive instruments. Comparing instantaneous fluxes over horizontal domains of (~10km)², the radiative closure is considered successful for flux differences smaller 10 W/m². When converting a BBR-measured radiance into a flux, the main challenge is assuming the present hemispheric field of outgoing radiances. Angular Distributions Models (ADMs) – mostly based on several years of satellite observations – provide these radiance fields. This work explores a new approach to SW ADMs and incorporates additional parameters (cloud-top effective radius and cloud-topped water vapor). When comparing against state-of-the-art methodology, new ADMs produce significantly different flux estimates of the order of 10 W/m².

Seminars & Colloquia
Most seminars at GISS are held during the academic year, September through May.
Formal seminar presentations by visiting scientists are held many Fridays at 11:00 a.m.
Informal lunchtime presentations by NASA GISS staff take place on Wednesdays at 1:00 p.m. about twice per month.
Other special seminars occur from time to time as visitors' schedules permit.
Security Note
Regulations require that visitors arrange in advance for a building pass. Persons attending a NASA GISS seminar or colloquium should contact the event host at least two days in advance of the event for assistance. Please include your affiliation in your e-mail.
Due to implementation of the REAL ID Act (2005), a state driver's license or identification card is currently (as of late 2018) required for admittance to the GISS premises, which is considered a federal facility. However, if you have a state-issued license or ID that is not considered REAL-ID compliant, you are urged to obtain one before entrance regulations change, which is expected to occur in 2020.
Persons who are not U.S. citizens or U.S. permanent residents and who may be planning a visit to GISS require that special arrangements be made. Please co-ordinate with your GISS host on this at least three weeks before your visit.
All visitors can expect to have their bags searched upon entry to GISS. This may include having to answer questions about personal items, including any medication the visitor may be carrying.
