Standard observation data of the equatorial troposphere and lower stratosphere taken by the EAR (NetCDF format)
ReleaseDate

Description
The 10-minute average observation data in the equatorial troposphere (2-20 km) taken by the equatorial atmosphere radar (EAR) at Kototabang, Indonesia (0.203S, 100.320E, 865m MSL), which has been operated in the standard observation mode of the troposphere and stratosphere. The data are stored in the netCDF file (Network Common Data Form) named (year)(month)(day).nc. The NetCDF file includes the range, height, time, three components of wind velocity, radial Doppler velocity, echo power, spectral width and noise level for each beam number and so on. The azimuth and zenith angles of beam 1, 2, 3, 4 and 5 are (0, 0), (0, 10), (90, 10), (180, 10) and (270, 10), respectively, in unit of degree. The value of 1.0e+10 means missing data.
