Earth Science: Analysis and Interpretation of Satellite-Based Spectroscopic Measurements

About the role

The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

Description

This opportunity is closed to applicants who are Senior Fellows (5-years or more past PhD).

The acquisition of a long-term data base on high-altitude ozone, total ozone, and ultraviolet (UV) solar irradiance by instruments in Earth orbit is now allowing detailed studies of the driving mechanisms of and the time scales involved in upper-atmospheric variability. In addition, spectroscopic measurements of the Earth's backscattered spectrum as seen from space reveal the presence and variability of trace gases, such as nitric oxide and sulphur dioxide.

• Projects currently under way include:
• (1) evaluation and analysis of the long-term changes in stratospheric ozone, especially changes in the Antarctic ozone hole;
• (2) evaluation of solar variability in the UV using measurements from the Nimbus 7 Solar Backscattered Ultraviolet (SBUV) spectral radiometer;
• (3) studies of the response of upper-atmospheric ozone to solar activity using Nimbus 4, Nimbus 7, and SBUV/2 measurements;
• (4) analysis of data from the Total Ozone Mapping Spectrometer on the effect of volcanic emissions (sulfur dioxide and aerosols) from the Mt. Pinatubo and other eruptions, on the reported ozone densities;
• (5) studies of the sensitivity of the SBUV measurement technique to anthropogenic and solar-related ozone perturbations;
• (6) analyses of test data from advanced SBUV instruments scheduled for future space flight.
