The Sea Surface Temperature (SST) data of the nearshore region of the North Pacific show temperature ranges in degrees C using points whose locations correspond to the centroids of AVHRR Pathfinder version 5 monthly, global, 4 km data set (PFSST V50). The pathfinder rasters are available from the Physical Oceanography Distributed Active Archive Center (PO.DAAC), hosted by NASA JPL. The data points in this dataset lie within a 20 km buffer from the GSHHS (Global Self-consistent, Hierarchical, High-resolution Shoreline) coastline. The GSHHS vector data are available from the National Geophysical Data Center (NGDC). Furthermore, each point in the SST dataset is categorized by the ecoregion in which it is located. This...

Advanced very high resolution radiometer (AVHRR) satellite data were acquired and composited into 14 day periods from 31 March 2000 to 12 October 2000 to map vegetation characteristics over the Alaskan landscape. Unique spatial and temporal qualities of the AVHRR data provide information that leads to a better understanding of regional biophysical characteristics of vegetation communities and patterns. These data provided synoptic views of the landscape and depicted phenological diversity, temporal vegetation phenology (green-up, peak of green, and senescence), photosynthetic activity, and regional landscape patterns. Products generated from the AVHRR composited data include a number of phenological datasets as...

The pathfinder rasters are available from the Physical Oceanography Distributed Active Archive Center (PO.DAAC), hosted by NASA JPL. The grid cells in this dataset lie within a 20 km buffer from the GSHHS (Global Self-consistent, Hierarchical, High-resolution Shoreline) coastline. The GSHHS vector data are available from the National Geophysical Data Center (NGDC). These data have been QA'd in that we have selected only data values with associated quality flags of...

In this study we present a technique to discriminate between climate or human-induced dryland degradation, based on evaluations of AVHRR NDVI data and rainfall data. Since dryland areas typically have high inter-annual rainfall variations and rainfall has a dominant role in determining vegetation growth, minor biomass trends imposed by human influences are difficult to verify. By performing many linear regression calculations between different periods of accumulated precipitation and the annual NDVImax, we identify the rainfall period that is best related to the NDVImax and by this the proportion of biomass triggered by rainfall. Positive or negative deviations in biomass from this relationship, expressed in the...

The data contained in this data set are derived from the NOAAAdvanced Very High Resolution Radiometer Multichannel SeaSurface Temperature data (AVHRR MCSST), which are obtainablefrom the Distributed Active Archive Center at the JetPropulsion Laboratory (JPL) in Pasadena, Calif. The JPL tapescontain weekly images of SST from October 1981 throughDecember 1990 in nine regions of the world ocean: NorthAtlantic, Eastern North Atlantic, South Atlantic, Agulhas,Indian, Southeast Pacific, Southwest Pacific, NortheastPacific, and Northwest Pacific.This data set represents the results of calculations carriedout on the NOAA data and also contains the source code of theprograms that made the calculations. The objective was...
