Observation data of the troposphere and lower stratosphere taken by the radiosonde soundings at Pontianak (netCDF format)

2016-07-21 16:57:00

Radiosonde sounding data at Pontianak, Indonesia (0.003S, 109.36E, 1m MSL) since November 11, 1996. The data are stored in the netCDF (network Common Data Form) file named (year)(month)(day)(hour)(minute).nc in universal time, for each launch of the balloon. The netCDF file includes launching universal date, launching universal time, time zone (hour), latitude, longitude, sea level, sonde serial number, time, height, pressure, temperature, relative humidity and zonal and meridional winds. The value of -999 means missing data.

If you acquire radiosonde data in Indonesia, we ask that you acknowledge us in your use of the data. This may be done by including text such as radiosonde data in Indonesia were provided by Research Institute for Sustainable Humanosphere of Kyoto University. We would also appreciate receiving a copy of the relevant publications.
