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 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 کاملAVHRR data processing for near real time applications
Polar orbiting satellites with low spatial resolution sensors, such as the AVHRR, provide repeated global coverage of the Earth. The data is directly transmitted to ground stations, and in some cases distributed immediately after the data acquisition. Near real time applications can be implemented if the adequate processing tools are available. This paper presents a near real time processing sy...
متن کاملRecommending Products using Preference Based Modeling
Common approaches to product recommendations are offer level propensity models and collaborative filtering. These methods are typically used for respectively a low or a high number of products, and come with specific limitations. In this paper we introduce preference based approaches to product recommendations, aimed at filling the gap between these methods. This approach can be used for any ex...
