Job description

Scientist for Algorithm Development and Validation with the Microwave Integrated Retrieval System

Department: UMD/ESSIC/CISESS 

Starting Salary: Commensurate with experience 

Closing Date: Friday, July 19, 2019 

Duties:

The University of Maryland/Earth System Science Interdisciplinary Center (UMD/ESSIC) has an opening for a researcher to work within the Cooperative Institute for Satellite and Earth System Studies-Maryland. The scientist will work directly on the algorithm development team for the Microwave Integrated Retrieval System (MiRS) within NOAA/NESDIS/STAR, which is the operational microwave only satellite retrieval algorithm (https://www.star.nesdis.noaa.gov/mirs/). MiRS is an inversion algorithm based on physical forward modeling and can invert observed multichannel radiances simultaneously to determine key components of the atmosphere and surface state: Atmospheric Temperature Profile, Atmospheric Water Vapor Profile, Total Precipitable Water, Land Surface Temperature, Surface Emissivity Spectrum, Sea-Ice Concentration, Snow Cover Extent, Snow-Water Equivalent, Integrated Cloud Liquid Water, Integrated Ice Water Path, Integrated Rain Water Path, Rainfall Rate, Snowfall Rate, Sea Ice Age, and Snow Grain Size.

General responsibilities will include algorithm maintenance and improvement, extension of the algorithm to new satellite/sensor systems, calibration/validation activities to assess retrieval performance, interaction with MiRS stakeholders, including operational users, other researchers, and NOAA management. Other activities include participation in algorithm and product readiness reviews, attendance at conferences, workshops, and meetings to present results to the scientific community. 

In particular, the successful candidate is expected to work on application of MiRS to anticipated data from the upcoming EUMETSAT Polar System – Second Generation (EPS-SG) mission, including data from the Microwave Sounder (MWS), Microwave Imager (MWI), and Ice Cloud Imager (ICI). The first satellite in the EPS-SG mission is scheduled for launch in 2022. Initial application of MiRS to EPS-SG will require analysis of the new instrument specifications and their relevance for likely retrieval products, as well as new software development to extend MiRS processing capability. Prior to launch simulated proxy data will be available to test updated software. It is anticipated that they will also take a leading role in enhancing and optimizing the capabilities of the current MiRS 1DVAR retrieval methodology. The successful candidate will also work on the assimilation of radiances from CubeSat observations as well as the assimilation of the satellite products.\

Qualifications:

The qualified candidate should have a PhD (preferred minimum of 5 years of experience) in remote sensing retrieval methods and radiative transfer modelling, especially using passive microwave or infrared measurements. Qualified candidates with an M.S. degree (preferred 10 years of experience) will also be considered. Additionally, demonstration of strong programming skills, particularly in Fortran90/95, C/C++, IDL, and Unix scripting is required. Strong scientific communication skills as demonstrated by refereed publications and conference presentations is also required.  This position requires U.S. citizenship or permanent resident status.
