Minimize NASA Postdoctoral Program - Earth Science: Analysis and Interpretation of Satellite-Based Spectroscopic Measurements (17690)

Date added: 22 May 2018

Organisation: NASA

Location: Maryland, USA

Application deadline: 01 July 2018

Description

The NASA Postdoctoral Program (NPP) offers US and international scientists the opportunity to advance their research while contributing to NASA's scientific goals. The NPP supports fundamental science; explores the undiscovered; promotes intellectual growth; and encourages scientific connections.

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; and
  6. analyses of test data from advanced SBUV instruments scheduled for future space flight.
