Job description
ESSIC and the Cooperative Institute for Satellite tv for pc Earth System Research (CISESS) of the College of Maryland, School Park, are searching for a scientist for the International Navigation Satellite tv for pc System (GNSS) Radio Occultation (RO) Calibration/Validation work.
The scientist will primarily work on the RO knowledge conversion from low-level GNSS observations to high-level profiles (e.g., bending angle) as a NOAA/NESDIS/STAR RO group member. GNSS RO is an energetic distant sensing approach that gives beneficial info on the vertical variations of electron density within the ionosphere and temperature, stress, and water vapor within the stratosphere and troposphere. The bending angle profiles derived from RO alerts have been utilized in operational numerical climate prediction (NWP) methods by way of knowledge assimilation to right temperature bias within the forecasts. The CISESS RO group helps NOAA’s RO satellite tv for pc processing and science purposes for the NOAA spine mission (i.e., COSMIC-2), the business RO missions, and NOAA companions’ missions.
The candidate will work with the group lead on evaluating/validating Exact Orbit Dedication (POD) outcomes for GNSS satellites and LEO (low Earth orbit) satellites, coding and upgrading scripts to automate the processing procedures from uncooked GNSS observations to high-level bending angle profiles. The candidate will carry out inter-satellite co-location RO profile comparisons and prediction of the situation of the RO profiles and count on occasional internet interface design for displaying outcomes.
The candidate is anticipated to contribute to the next:
- Design LEO or Small satellite tv for pc Exact Orbit Dedication (POD) algorithm with Bernese or different POD software program
- Routinely operating POD software program and different positioning software program to supply and evaluate/validate the satellite tv for pc orbital ephemeris and clock bias outcomes from different RO facilities.
- Coding scripts and automation for low-level to high-level RO knowledge conversion.
- Supporting inter-LEO extra part/bending angle comparisons from totally different processing procedures/facilities.
- Algorithm implementation for RO processing on totally different ranges.
- Assist with easy web-contents design for displaying RO outcomes on totally different ranges.
- Publish analysis ends in peer-reviewed journals and take part in conferences.
{Qualifications}:
Information, Expertise, and Talents:
- Sturdy Expertise with code improvement in FORTRAN/C/Python, script language (bash, Perl, and so forth.) in Linux/Unix environments, and visualization coding in IDL and/or Matlab.
- Expertise processing giant quantities of the observational dataset utilizing a number of threads/clusters.
- Expertise with normal knowledge format, e.g., netCDF-4, BUFR, GRIB, and so forth.
- Accustomed to GNSS positioning idea and a minimum of one GNSS/LEO satellite tv for pc POD software program.
Desired Expertise:
- Understanding GNSS positioning idea and geodetic datum
- Understanding LEO satellite tv for pc Radio Occultation idea.
- Confirmed means to work effectively in a group atmosphere
- Related peer-reviewed publications
- Good writing and oral communication expertise
{Qualifications}:
