I am Lauryn Fox from Saint Petersburg, Florida. Growing up in this beautifully stormy part of Florida and a love for math is what guided me to studying meteorology. I hope to continue my pursuit of research into my career.

Potential Atmospheric Reanalyses for Improving Research Vessel Data Quality Control

Abstract

Having access to long-term, widespread, and accurate weather data is a staple of climate studies. The purpose of the Shipboard Automated Meteorological Oceanographic Systems project is to publish quality-assured weather data over the oceans to provide accurate values to a diverse research community. SAMOS receives data from 44 research vessels on which it runs automated quality control processes, which places flags on unlikely values. The values that are a standard of plausibility come from a climatology, which comes from a historic atmospheric analysis. The current one used for the SAMOS project by Da Silva, only uses in situ measurements and is becoming outdated compared to current technology, so a new reanalysis could be a better asset to the SAMOS quality control process. Each atmospheric reanalysis has its benefits and limitations for the sake of the project, so each must be tested and compared. The ERA5 reanalysis seems to be a promising option that is worth comparing the results of a climatology test between it and the existing Da Silva climatology. By assigning flags to the implausible values when comparing a year of SAMOS observations to the ERA5 climatology, and examining the results of the same year with the current SAMOS climatology, the two can be evaluated and compared.
