Validation Test Report for NFLUX PRE: Validation of Specific Humidity, Surface Air Temperature, and Wind Speed Precision and Accuracy for Assimilation into Global and Regional Models
Abstract
The Naval Research Laboratory (NRL) Ocean Surface Flux System Version 1 (NFLUX) provides observation processing, quality control, and analysis of measurements of ocean surface state variables for application with ocean models. The NFLUX system consists of three components: processing satellite retrievals of ocean surface state variables (NFLUX PRE), automated quality control of the observations (NFLUX QC), and 2D variational analyses of the satellite and in situ data with atmospheric models (NFLUX VAR). This document will review and present the current capability of the first component of the NFLUX system NFLUX PRE. The NFLUX QC and NFLUX VAR components leverage the Navy Coupled Ocean Data Assimilation (NCODA) system to support the quality control and analysis; these two components are described in a separate report. The NFLUX system was developed to address the requirement for accurate representation of the ocean/atmosphere interface in Navy ocean models. Unlike atmospheric models that are required to represent the entire vertical aspect of the 4D atmosphere, the NFLUX system provides products only for ocean surface state variables. The NFLUX Version 1 products are: specific humidity (Qa) at a height of 5 meters, surface air temperature (Ta) at a height of 5 meters, and scalar surface wind speed (U10) at a height of 10 meters.
