A Probabilistic Derivation of Heidke Skill Score
Publisher: American Meteorological Society
Abstract: n alternative derivation of Heidke skill score for 2 ? 2 tables is presented, starting from the assumption that a categorical forecast is useful, if the probability of an occurrence of an event, given the forecast, is ...
New Geostationary Satellite–Based Snow-Cover Algorithm
Publisher: American Meteorological Society
Abstract: now cover plays an important role in the climate system by changing the energy and mass transfer between the atmosphere and the surface. Reliable observations of the snow cover are difficult to obtain without satellites. ...
Social Media as a Source of Meteorological Observations
Publisher: American Meteorological Society
Abstract: An increasing number of people leave their mark on the Internet by publishing personal notes (e.g., text, photos, videos) on Web-based services such as Facebook and Flickr. This creates a vast source of information that ...
Validation of Automatic Cb Observations for METAR Messages without Ground Truth
Publisher: American Meteorological Society
Abstract: n aviation meteorology, METAR messages are used to disseminate the existence of cumulonimbus (Cb) clouds. METAR messages are traditionally constructed manually from human observations, but there is a growing trend toward ...
Comparison of Satellite Cloud Masks with Ceilometer Sky Conditions in Southern Finland
Publisher: American Meteorological Society
Abstract: The cloud mask is an essential product derived from satellite data. Whereas cloud analysis applications typically make use of information from cloudy pixels, many other applications require cloud-free conditions. For this ...
Comparison of Snow Cover from Satellite and Numerical Weather Prediction Models in the Northern Hemisphere and Northern Europe
Publisher: American Meteorological Society
Abstract: Snow cover has a strong effect on the surface and lower atmosphere in NWP models. Because the progress of in situ observations has stalled, satellite-based snow analyses are becoming increasingly important. Currently, there ...
Estimation of Surface Solar Global Radiation from NOAA AVHRR Data in High Latitudes
Publisher: American Meteorological Society
Abstract: A physical method for estimating the instantaneous global irradiance and daily cumulative insolation based on Advanced Very High Resolution Radiometer data was developed and tested at high latitudes in a boreal subarctic ...
MetOp/AVHRR Snow Detection Method for Meteorological Applications
Publisher: American Meteorological Society
Statistical Learning Methods as a Basis for Skillful Seasonal Temperature Forecasts in Europe
Publisher: American Meteorological Society
Abstract: AbstractA statistical learning approach to produce seasonal temperature forecasts in western Europe and Scandinavia was implemented and tested. The leading principal components (PCs) of sea surface temperature (SST) and ...
The Helsinki Testbed: A Mesoscale Measurement, Research, and Service Platform
Publisher: American Meteorological Society
Abstract: The Finnish Meteorological Institute and Vaisala have established a mesoscale weather observational network in southern Finland. The Helsinki Testbed is an open research and quasi-operational program designed to provide ...
