| Description: |
| The time-range plots of the echo power in the ionosphere above 80 km taken by the equatorial atmosphere radar (EAR) at Kototabang, Indonesia (0.20S, 100.32E, 865m MSL), which has been operated in the field-aligned irregularity (FAI) observation mode. The display of time-range plots of the echo intensity depends on each observation parameter. The time ranges are two kinds of local day (06-18 h, LT) and night (18-06 h, LT). The plots are stored in the gif file named (month)(day)(year).(start local time).(observation parameter).rti.mul.snr.png. The local date, start and end time, and observation parameter are described at the top center of each PNG plot. Details of the observation parameter are described in the EAR-FAI homepage (http://www.rish.kyoto-u.ac.jp/ear/data-fai/index.html). |

| Instrument: |
| Name: Equatorial Atmosphere Radar (EAR) |
| Description: Equatorial Atmosphere Radar (EAR) is a large Doppler radar built for atmospheric observation at the equator in West Sumatra, Indonesia (0.20S, 100.32E, 865m MSL). The construction was completed in March 2001, with collaboration between RISH, Kyoto University and the National Institute of Aeronautics and Space of Indonesia (LAPAN) of Indonesia. The EAR has a circular antenna array of approximately 110 m in diameter, which consists of 560 three-element Yagis. It is an active phased array system with each Yagi driven by a solid-state transceiver module. This system configuration makes it possible to direct the antenna beam by electronic control up to 5000 times per second. The EAR transmits an intense radio wave of 47 MHz to the sky and receives extremely weak echoes scattered back by atmospheric turbulence. It can observe winds and turbulence in the altitude range from 2 km to 20 km (troposphere and lower stratosphere). It can also observe echoes from ionospheric irregularities at heights more than 80 km. |

| Description: The Equatorial Atmosphere observatory at Kototabang is located at the equator in West Sumatra, Indonesia (0.20S, 100.32E, 865m MSL). In this site, various kinds of instruments (for example, boundary layer radar (BLR), equatorial atmosphere radar (EAR) and meteor wind (MW) radar) have been installed, which measure the equatorial atmosphere including the troposphere, lower stratosphere, upper mesosphere, thermosphere and ionosphere. |
