A New Method to Produce Sea Surface Temperature Using Satellite Data Assimilation into an Atmosphere–Ocean Mixed Layer Coupled Model
(American Meteorological Society, 2013)new method of producing sea surface temperature (SST) data for numerical weather prediction is suggested, which is obtained from the assimilation of satellite-derived SST into an atmosphere?ocean mixed layer coupled model. ... -
The Design and Development of an Irish Sea Passenger-Ferry-Based Oceanographic Measurement System
(American Meteorological Society, 2012)n evolving coastal observatory has been hosted by the National Oceanography Centre at Liverpool, United Kingdom, for more than nine years. Within this observatory an instrumented ferry system has been developed and operated ... -
Evaluation of ASCAT-Based Daily Gridded Winds in the Tropical Indian Ocean
(American Meteorological Society, 2013)he quality of daily gridded Advanced Scatterometer (ASCAT; DASCAT) blended winds is examined in the tropical Indian Ocean using 3-day running mean gridded Quick Scatterometer (QuikSCAT; QSCAT) winds and in situ daily winds ... -
Long-Term Nitrate Measurements in the Ocean Using the in situ Ultraviolet Spectrophotometer: Sensor Integration into the APEX Profiling Float
(American Meteorological Society, 2013)eagent-free optical nitrate sensors [in situ ultraviolet spectrophotometer (ISUS)] can be used to detect nitrate throughout most of the ocean. Although the sensor is a relatively high-power device when operated continuously ... -
Calibration and Stability of Oxygen Sensors on Autonomous Floats
(American Meteorological Society, 2013)he calibration accuracy and stability of three Aanderaa 3835 optodes and three Sea-Bird Electronics SBE-43 oxygen sensors were evaluated over four years using in situ and laboratory calibrations. The sensors were mostly ... -
Speeding Up the Computation of WRF Double-Moment 6-Class Microphysics Scheme with GPU
(American Meteorological Society, 2013)he Weather Research and Forecasting model (WRF) double-moment 6-class microphysics scheme (WDM6) implements a double-moment bulk microphysical parameterization of clouds and precipitation and is applicable in mesoscale and ... -
Development of the Upgraded Tangent Linear and Adjoint of the Weather Research and Forecasting (WRF) Model
(American Meteorological Society, 2013)he authors propose a new technique for parallelizations of tangent linear and adjoint codes, which were applied in the redevelopment for the Weather Research and Forecasting (WRF) model with its Advanced Research WRF dynamic ... -
