Elementor #927


I’m Judy Hertz. In the dawn of time I sat for my 100-ton U.S. Coast Guard Ocean Operator (captain’s) license and my Series 7 National Association of Securities Dealers (broker’s) license, then went to work for NASA HQ as an IT Project and UNIX Systems manager. Riotsystems is the consultancy I founded in 1996.

atmospheric woman

I’m semi-retired as of July 2020, from a recent contract working as the Climate Data Analyst for the NASA Center for Climate Simulation (NCCS) Collaborative REAnalysis Technical Environment (CREATE) team. A bit of information on that is below…

Cool maps from my reanalysis work

from a 2016 Ocean Reanalysis poster session at the American Geophysical Union fall meeting
January 1998 (left) Warmer Eastern Equatorial Pacific than January 1999 (right)

This project developed ensemble average and standard deviation for potential temperature, salinity, and zonal and meridional velocities from eight ocean reanalyses (syntheses), 1980-2010.

In the maps, note the differences in potential temperature (theato), with the January 1998 ensemble average at 112.5 meter depth °C (left) showing a significantly warmer eastern equatorial Pacific during the peak of the warming associated with the 1997-98 El Niño than the January 1999 ensemble average at 112.5 meter depth °C (right) during the subsequent La Niña cold event.

Hadoop Ecosystem Projects for NASA GSFC NCCS
I developed prototyped systems for the NASA GSFC Center for Computational Sciences (NCCS) using Modern-Era Retrospective Analysis for Research and Applications (MERRA) data collections and Apache Hadoop (HiveQL and Impala SQL) on physical clusters and Linux containers.
CERES Satellite Data with Climate Ontology for NASA/Cray

Our NASA LaRC team collaborated with Cray to convert Clouds and the Earth’s Radiant Energy System (CERES) datasets to Resource Description Framework (RDF) triples and load into a triple store residing on YarcData‘s Urika, an in-memory appliance for graph analytics.

App and Ontology Design for NASA GSFC CISTO

Two projects use our app-based climate ontology to aid climate scientists’ variable conversion from MERRA and Tropical Rainfall Measuring Mission (TRMM) — for NASA GSFC Computational and Information Sciences and Technology Office (CISTO).
