NPP dataset in the Heihe River Basin (1998-2002)


The annual total net primary productivity (NPP) and average productivity of different ecosystems in heihe river basin from 1998 to 2002 were estimated by using the light energy utilization model c-fix, high spatial and temporal resolution remote sensing data of SPOT/VEGETATION, global grid meteorological reanalysis data and land use map of heihe river basin.

From 1998 to 2002, the 10-day 1-km resolution SPOT VEGETATATION NDVI (10-day maximum synthesis) data product in the heihe basin, provided by the image processing and archiving center (CTIV) of VITO institute, Belgium, was used to calculate the key parameters fAPAR required by the c-fix model.

The daily temperature and total radiation of heihe river basin from 1998 to 2002 were obtained using a global 1.5 °× 1.5 ° grid meteorological data product from MeteoFrance.

It contains the spatial distribution pattern of annual accumulation of NPP in heihe basin and the seasonal dynamic map of NPP.The spatial resolution of this data is 1km.


Data file naming and use method

File naming: the data is stored in grid format, and the folders are divided into "Albers" and "Geographic" for the Albers projection and geographical coordinate system.File name "nppyyyy1kmalb", in which yyyy represents the year, for example npp19981kmalb, represents the 1km NPP spatial distribution pattern in 1998.
Data reading: remote sensing software such as Arcgis can be used to open and read, and the data can be expressed in raster images.
