GAW Report, 243. Report of the Fifth Erythemal UV Radiometers Intercomparison
This report presents the background information, procedures and results of the intercomparison of erythemal UV sensors carried out at the Central Observatory of Buenos Aires (OCBA) in 2018 against reference radiometers calibrated at the World Radiation Center (PMOD/WRC) in Davos during 2017. In this way, the data obtained at the measurement sites will be standardized and will be comparable locally and globally. Twenty sensors were calibrated, belonging to Argentine monitoring and research institutions. The associated relative uncertainty of each sensor was also estimated.
GOES-R Series Faculty Virtual Course: Severe Storms
In this webinar recording, Michael Bowlan explains how GOES-R/16 can help improve forecasts of severe storms and provide forecasters with real-time information about lightning, flooding potential and other hazards. The high-resolution Advanced Baseline Imager (ABI) data can indicate whether thunderstorm updrafts are gathering strength or weakening, helping aid forecasters in making warning decisions. The ABI can also aid in identifying storms and convective complexes that have stalled or are “training”, which can signal a flood risk and help forecasters issue flood or flash flood warnings soon ...
GOES-R Series Faculty Virtual Course: Tropical Cyclones
In this webinar recording, Andrea Schumacher demonstrates the GOES-R series' new capabilities for real-time tropical cyclone analysis and monitoring, which will contribute significantly to improved hurricane track and intensity forecasts. The GOES-16 imager will provide dramatic new views of tropical cyclone phenomena, offering vastly improved time and spatial resolution as well as color composite images to enhance cloud bands and other features. This webinar will also explore the role of the Geostationary Lightning Mapper (GLM) in helping identify areas of strong thunderstorms associated with ...
GOES-R Series Faculty Virtual Course: Advanced Baseline Imager
In this webinar recording, Tim Schmit demonstrates the improved temporal, spatial, spectral and calibration attributes of the Advanced Baseline Imager (ABI) on the GOES-R series. The main uses for each of the sixteen spectral bands will be covered, using examples from the recently launched GOES-16 ABI. Imagery and data loops for various types of atmospheric phenomena will be presented to illustrate the improved spectral capabilities and higher temporal and spatial resolution of the ABI. This is a recorded webinar presented by an instructor at his home institution. Audio variations may exist.
GOES-R Series Faculty Virtual Course: Aviation Products
In this webinar recording, Amanda Terborg (with input from Dr. Chad Gravelle), will demonstrate the capabilities of GOES-R/16 in analyzing hazards affecting the aviation industry. The talk focuses specifically on four hazards (but there are others): 1) fog and low stratus, 2) in-flight turbulence, 3) dust, and 4) volcanic ash. Through the use of GOES-R/16 spectral bands, band differences, and RGB composites, satellite data users can detect the development and evolution of aviation threats better than with any previous geostationary satellites. This is a recorded webinar presented by an instruc ...

Cloud effects on erythemal UV radiation in a complex topography
Walker Daniel - Confédération Suisse, 2010UV radiation is part of the solar spectrum with wavelengths between 100 and 400 nm. In this study, erythemal UV is investigated; a measure directly related to the harmfulness of
solar radiation to our skin. UV radiation has important impacts on di?fferent ecosystems, life and also on public health. Therefore, detailed information about the spatial distribution of UV radiation and its temporal evolution is required. Since observations are spatially and temporally sparse, these issues are often approached by radiative transfer modeling. These models perform well for simulating UV radiatio ...

Radiation processes in the atmosphere : Second IMO Lecture
This monograph on atmospheric radiation, by one of the world's foremost specialists, gives an up-to-date review of a subject of increasing importance to meteorology. Particular attention is paid to the interaction between dynamic and radiative processes, a topic of major relevance to the numerical modelling of atmospheric circulation, especially for the purpose of long-range weather forecasting. Various chapters deal with the solar constant, radiation characteristics of the underlying surface, radiation climatology of the Earth, atmospheric aerosols and their influence on radiation transfer, t ...
