RISSpectral Absorption of Solar Radiation in Cloudy Atmospheres: A 20 cm−1 Model
Publisher: American Meteorological Society
Abstract: The spectral of solar radiation in typical water clouds is determined using a radiative transfer model based on LOWTRAN transmission functions at a 20 cm?1 resolution and Monte Carlo simulations of photon pathlength ...
A Preliminary Analysis of Spatial Variability of Raindrop Size Distributions during Stratiform Rain Events
Publisher: American Meteorological Society
Abstract: The spatial variability of raindrop size distributions (DSDs) and precipitation fields is investigated utilizing disdrometric measurements from the four Precipitation Occurrence Sensor Systems (POSS) and radar reflectivity ...
Quality Control and Tilt Correction Effects on the Turbulent Fluxes Observed at an Ocean Platform
Publisher: American Meteorological Society
Abstract: This study investigates atmospheric factors influencing the quality and the postprocessing (e.g., tilt correction) of fast-response measurements of turbulent fluxes for difficult open-sea measurements over an offshore ...
Evaluation of Boundary Layer Similarity Theory for Stable Conditions in CASES-99
Publisher: American Meteorological Society
Abstract: The Monin?Obukhov similarity theory and a generalized formulation of the mixing length for the stable boundary layer are evaluated using the Cooperative Atmosphere?Surface Exchange Study-1999 (CASES-99) data. The large-scale ...
Use of the Doppler Spectral Width to Improve the Estimation of the Convective Boundary Layer Height from UHF Wind Profiler Observations
Publisher: American Meteorological Society
Abstract: Enhancement of the air refractive index structure parameter C2n often occurs at the top of the convective boundary layer (CBL), where the absolute values of the vertical gradients of virtual potential temperature and mixing ...
The Hydrometeor Classification Algorithm for the Polarimetric WSR-88D: Description and Application to an MCS
Publisher: American Meteorological Society
Abstract: This paper contains a description of the most recent version of the hydrometeor classification algorithm for polarimetric Weather Surveillance Radar-1988 Doppler (WSR-88D). This version contains several modifications and ...
Identification and Removal of Ground Echoes and Anomalous Propagation Using the Characteristics of Radar Echoes
Publisher: American Meteorological Society
Abstract: This paper explores the removal of normal ground echoes (GREs) and anomalous propagation (AP) in ground-based radars using a fuzzy logic approach. Membership functions and their weights are derived from the characteristics ...
