A dataset of estimated net primary production of Japanese cedar plantations (ver.1)

# Abbreviations in this text
NPP:        Net Primary Production, average of stand ages 36-40
GCM:        Global Climate Model
HT:            Historical Trend, average of five years 1996-2000
FP2050:        Future Prediction, average of five years 2046-2050
FP2100:        Future Prediction, average of five years 2096-2100 (except for a GCM HadGEM2-ES of 2095-2099)

# Description
The data is prepared as four files in tab-delimited text format or ten netcdf files in a zip file. The annual NPP of cedar plantations under current and future climates are calculated in 196928 meshes in Japan. The climate scenarios used are owned and distributed by the third party (National Agriculture and Food Research Organization, Japan). For the methodology on modeling, parameterization and nation-wide calculation, please check the paper below.

# npp_netcdf.zip (594 MB)
The 10 files in netcdf format are compiled in a zip file for NPP data of different RCP scenarios and GCMs.
Please check the content of each file by following command.
ncdump -h filename

# summary_map.zip (5.8 MB)
The 20 files in png format are compiled in a zip file for maps of NPP and its change. The maps were created using the Generic Mapping Tools version 5 (http://gmt.soest.hawaii.edu/). The average values of five GCMs are used for mapping.
