ODIAC Fossil Fuel CO2 Emissions Dataset

Oda Tomohiro
The Open-Data Inventory for Anthropogenic Carbon dioxide (ODIAC) is a high spatial resolution emission dataset for CO2 emissions from fossil fuel combustion (Oda and Maksyutov, 2011). In 2009, the original version of ODIAC was developed by Drs. Tomohiro Oda (now at USRA/NASA Goddard) and Shamil Maksyutov at the Greenhouse Gases Observing SATellite (GOSAT) project, National Institute for Environmental Studies (NIES). ODIAC first introduced the combined use of nightlight data and individual power plant emission/location profiles...

Wind Profiler at NICT Tokyo (1993-2003)

Ohno Yuichi
Wind profiler is a Doppler radar for measuring wind from the ground. It can measure wind vectors above the radar site utilizing the clear-air echo. Clear-air echo is caused by fluctuation of the refractive index in which the scale is half the radar wavelength (Bragg scattering). From the Doppler shift of along a certain beam direction, the line-of-sight velocity along the radar beam can be measured. Assuming horizontal homogeneity of wind field, three components of...

Continuous Observational Data of Atmospheric CO2 Mixing Ratios at Cape Ochi-ishi

Mukai Hitoshi
The present data set is a set of continuous observational data of background CO2 mixing ratios in the vicinity of 40°N in the northern region of East Asia, measured at Cape Ochi-ishi situated on Nemuro Peninsula, Hokkaido, Japan. Because Cape Ochi-ishi, stretching into the Pacific Ocean, has a low population density and because the cape itself is a protected area with limited access, it is subjected to very small influence from local anthropogenic CO2 emissions....

Continuous Observational Data of Atmospheric CO2 Mixing Ratios on Hateruma Island

Mukai Hitoshi
The present data set is a set of continuous observational data of background CO2 mixing ratios in the vicinity of 20°N in the Western Pacific Ocean facing East Asia, measured on Hateruma Island, Okinawa Prefecture, Japan. Hateruma Island is a small island with a diameter of approx. 5 km. Because it is subjected to very small influence from local terrestrial ecosystem and/or anthropogenic CO2 emissions, the daily variations are small and the CO2 mixing ratios...

Wp Index

The Wp index was proposed by Nose et al. [2012] to measure the Pi2 wave power at low latitude. It is derived from 1-s geomagnetic field variations in the H component measured at 11 stations at low latitude.

Manually scaled parameters of Ionogram at Wakkanai, Japan

Ishii Mamoru
Ionospheric parameters are manually scaled from ionograms which are obtained at Wakkanai, Hokkaido, Japan by the swept frequency ionosonde for the range between 1 and 30 MHz. Scaled parameters are the ordinary-mode critical frequencies (foE, foF1, foF2) and the minimum virtual heights (h'E, h'F1, h'F2) corresponding to E (90-120 km), and F (> 120km) layers of the ionosphere; and the minimum observation frequency (fmin), which can be a measure of the D (80-90 km) region...

Ionogram at Wakkanai, Japan

Ishii Mamoru
The ionogram is recorded tracings of high-frequency (HF) radio pulses reflected in the ionosphere. It is produced by the vertical incidence ionospheric sounder (ionosonde) at Wakkanai, Hokkaido, Japan. The sounding frequency is swept from 1 to 30 MHz. The height is calculated from the traveling time of the sounding radio wave and the light velocity, i.e., virtual height. Echo traces are composed of ordinary and extraordinary mode by the effect of the Earth's magnetic field...

The dataset is intended for use in a model intercomparison (MIP) study, called GTMIP, which is a part of the Japanese-funded Arctic Climate Change research project. In order to prepare a set of site-fitted forcing data for LSMs with realistic yet...

Mesospheric wind velocity data (30min. mean) observed with MF radar at Poker Flat, Alaska

Murayama Yasuhiro
Horizontal wind velocity in the altitude range of approx. 60-90 km is observed with Poker Flat MF (medium frequency) radar, using the radar wave at 2.43 MHz. The radar receives weak radio echo signals returned from the weakly ionized atmosphere (ionospheric D-region) at the target altitudes, to deduce horizontal air motions (Murayama, Y., K. Igarashi, D. D. Rice, B. J. Watkins, R. L. Collins, K. Mizutani, Y. Saito, and S. Kainuma, Medium Frequency Radars in...
