The AVHRR Polar Pathfinder Climate Data Records
With recent, dramatic changes in Arctic sea ice and the Antarctic ice sheets, the importance of monitoring the climate of the polar regions has never been greater. While many individual global satellite products exist, the AVHRR Polar Pathfinder products provide a comprehensive set of variables that can be used to study trends and interactions within the Arctic and Antarctic climate systems. Th...
متن کاملSeasonality of Pathfinder Avhrr Land Ndvi Data for Northeastern Brazil
The Normalized Difference Vegetation Index (NDVI) was used to characterize the seasonal variation of land cover over the Northeastern Brazil (NEB) with the NOAA/NASA Pathfinder AVHRR Land (PAL) data set. Twenty years of monthly spatial-aggregated NDVI climatology was determined by calculating lower, mean, and upper NDVI values using a 0.5 lat by 0.5 log grid cell size. The results indicated tha...
متن کاملThe Scatterometer Climate Record Pathfinder
While originally designed for ocean wind measurement, radar scatterometers have proven to be very effective in monitoring land cover and ice conditions and in climate studies. The NASA Scatterometer Climate Record Pathfinder (SCP) project has generated a unique climate data record from the series of historic and ongoing scatterometer missions. Image data are archived from the SeaWinds on QuikSC...
متن کاملThe potential of Pathfinder AVHRR data for providing surrogate climatic variables across Africa and Europe for epidemiological applications.
Surface climatic conditions are key determinants of arthropod vector distribution and abundance and consequently affect transmission rates of any diseases they may carry. Remotely sensed observations by satellite sensors are the only feasible means of obtaining regional and continental scale measurements of climate at regular intervals for real-time epidemiological applications such as disease ...
متن کاملImpact of AVHRR Channel 3b Noise on Climate Data Records: Filtering Method Applied to the CM SAF CLARA-A2 Data Record
A method for reducing the impact of noise in the 3.7 micron spectral channel in climate data records derived from coarse resolution (4 km) global measurements from the Advanced Very High Resolution Radiometer (AVHRR) data is presented. A dynamic size-varying median filter is applied to measurements guided by measured noise levels and scene temperatures for individual AVHRR sensors on historic N...
