Meteorological Analysis (CMA) Data along the Northern Gulf Coast between April 2015 and December 2016Consortium for Oil Spill Exposure Pathways in Coastal River-Dominated Ecosystems (CONCORDE)

||||||||||||||||||||
Abstract:
A gridded hourly database at 0.01 degree spacing for the northern Gulf of Mexico, the CONCORDE Meteorological Analysis (CMA), was developed from April 2015 to December 2016. It combines 4 data sources to create 13 meteorological parameters in NetCDF format. Data sources include: the Real-Time Mesoscale Analysis (RTMA), the North American Mesoscale Forecast System (NAM), the Next Generation Weather Radar (NEXRAD), and the Advanced Very High Resolution Radiometer (AVHRR). These data sources provide 2-meter temperature, relative humidity, surface pressure, 10-meter u and v wind components, sea surface temperature, cloud fraction, downward shortwave radiation flux, downward longwave radiation flux and one hour precipitation total. Additional parameters including the surface u and v momentum stresses, and sensible heat flux, were calculated using the Florida State University’s Coupled Ocean-Atmosphere Response Experiment (COARE) algorithm.
Purpose:
The necessity of high-resolution atmospheric forcing for the ocean model development motivated the creation of a long-term dataset known as the CONCORDE Meteorological Analysis (CMA). CMA consists of hourly reanalysis of 2-m temperature, relative humidity, surface pressure, 10-m u and v wind components, sea surface temperature, cloud fraction, downward shortwave radiation flux, downward longwave radiation flux, 1-h precipitation total, surface u and v momentum stresses, and sensible heat flux at 0.01° grid spacing. The surface momentum and thermodynamic fields are processed from the Real-Time Mesoscale Analysis (RTMA). RTMA (De Pondeca et al. 2011) is a 2.5-km 2DVAR product which uses the High Resolution Rapid Refresh (HRRR) model forecast (Benjamin et al. 2016) for the background field, adjusted with surface observations with a non-isotropic recursive filter (Purser et al. 2003). The RTMA data assimilation procedure matches observed surface data, captures mesoscale and diurnal patterns, and provides a coherent field that best matches the geographically-related features. Fitzpatrick and Lau (2017) performed a validation study of CMA versus buoys and inland observations for spring, summer, and fall 2015, and noted speed errors of 0.5-1.5 ms-1, wind direction errors of 14-21 deg, and temperature errors of 0.5-1.0°C. CMA’s radiation parameters and total cloud cover percentage are from North American Mesoscale Forecast System (NAM) forecast fields. The Next Generation Weather Radar Level-III provides the hourly precipitation totals on a 0.24-km by 1° grid based on a dual polarization Quantitative Precipitation Estimate (QPE) algorithm. Radar data from top of each hour are used from Slidell, LA or Mobile, AL are used based on closer proximity to the analysis grid point, then interpolated by nearest neighbor. The Advanced Very High Resolution Radiometer provides daily sea surface temperature in 1.09 km resolution. Quality control is applied and a 10-day running mean was used. The Florida State University’s Coupled Ocean-Atmosphere Response Experiment flux algorithm calculates the sensible heat flux and surface momentum stresses. All data is either bilinearly interpolated or uses near-neighbor. The CMA dataset begins in April 2015, and covers through Dec. 2016.
