The present work aims at examining the association of nighttime temperature inversions and synoptic-scale circulation in the Athens basin. Temperature inversions have a direct impact in the diffusion and transport of pollutants, a fact that highlights the importance of investigating their cause effect relationship. For this purpose, randiosonde measurements from the upper-air station in Hellini...
Remote sensing instruments and sensors have made significant progress over the last several decade in spatial, spectral and temporal resolutions. These improvements have led to the collection of synoptic scale data and enabled a variety of new applications. For example, improvements in temporal resolution allows monitoring biomass on a daily basis. Improvements in spatial resolution allows fine...
Concern over the health of coral reef communities has greatly intensified in recent years, particularly with regard to the complex dynamics of global change. The synoptic spatial and temporal monitoring capabilities of remote sensing provide a valuable avenue for evaluating the impacts of local, regional and global change on this important natural resource. Hyperspectral imagery acquired over t...
We describe the first simulation experiment and output archives of the Project to Intercompare Regional Climate Simulations (PIRCS). Initial results from simulations of the summer 1988 drought over the central U.S. indicate that limited-area models forced by large-scale information at the lateral boundaries are able to reproduce bulk temporal and spatial characteristics of meteorological fields...
While it is generally recognized that clouds play an important role in the climate system, many fundamental cloud properties have not been extensively observed. Clouds can be described on multiple spatial and temporal scales. At the largest scales, the patterns of cloud systems denote synoptic scale motions. These patterns are, however, strongly modulated by mesoscale atmospheric motions and in...
[1] Patterns of ocean current variability are examined on the West Florida Shelf by a neural network analysis based on the self-organizing map (SOM), using time series of moored velocity data that span the interval October 1998–September 2001. Three characteristic spatial patterns are extracted in a 3 4 SOM array: spatially coherent southeastward and northwestward flow patterns with strong curr...
Satellite remote sensing, with its unique synoptic coverage capabilities, can provide accurate and immediately valuable information on fire analysis and post-fire assessment, including estimation of burnt areas. In this study the potential for burnt area mapping of the combined use of Artificial Neural Network (ANN) and Spectral Angle Mapper (SAM) classifiers with Landsat TM satellite imagery w...
The combination of measurements from different satellite instruments for the estimation of precipitation is a promising way to overcome the shortcomings of measurements from a single data source. EUMETSAT realised the Multi-sensor Precipitation Estimate (MPE) in order to combine the advantages of the high temporal and comparably high spatial resolution of a geostationary IR sensor with the high...
Reliable forecasts for the dispersion of oceanic contamination are important for coastal ecosystems, society, and the economy as evidenced by the Deepwater Horizon oil spill in the Gulf of Mexico in 2010 and the Fukushima nuclear plant incident in the Pacific Ocean in 2011. Accurate prediction of pollutant pathways and concentrations at the ocean surface requires understanding ocean dynamics ov...
