Official information on J-OFURO3 data set


This page describes the instructions to download J-OFURO3 data set.

INTRODUCTION

All publicly available data sets can be downloaded from the official J-OFURO website (here).
For the purpose of your scientific research, you can download our data set and use it freely.
For the other purposes including business, please contact us before using our data from this form.

FILE NAME and FORMAT

Data files provided by J-OFURO3 are grouped by variable name (VAR), temporal resolution (TR), spatial resolution code (SR), dataset version code (VER), and year (YYYY). Data files are named under the following rules.

J-OFURO3_VAR_VER_TR_SR_YYYY.nc

VAR: variable name
VER: version code(ex. Vm.n)
TR: temporal resolution(DAILY / MONTHLY / CLM)
SR: spatial grid(HR: 0.25 degree grid or LR: 1.0 degree grid)
YYYY: four-digit year(e.g., 2013 )

Data file format is a self-descriptive netCDF. File extension is ”.nc”.
You can use the netCDF files by an analysis software (e.g., GrADS; Ferret)
