Observation data of the lower troposphere taken by the boundary layer radar (BLR)-1 at Shigaraki (GIF format)

2016-07-21 18:25:00

The time-height plots of the three components of wind velocity (zonal, meridional and vertical winds), the echo power and spectral width of three radar beams in the lower troposphere between 0.5 and 6.5 km taken by the boundary layer radar (BLR)-1 at Shigaraki in the prefecture, Japan (34.86N, 136.11E, 385m MSL). The plots are stored in the gif file named (year)(month).(variable).gif for one month plot or (year)(month)(day).(variable).gif for one day plot. The variable abbreviations are wnd, pwr and wdt, which mean wind velocity, echo power and spectral width, respectively. Local time is used for time. The right panels of each time-height plot are 1-day or 1-month average profiles of each parameter as a function of height. The missing data are presented by white color.

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