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...

Ocean Renalysis

The 4D-VAR assimilation system used here is the same as in Masuda et al. [2003] covering the global ocean. The OGCM is version 3 of the GFDL Modular Ocean Model (MOM; Pacanowski and Griffies, 1999), which is equipped with several sophisticated parameterization schemes, for example, nonlocal K Profile Parameterization (Large et al., 1994) for mixed layer physics, Gent and McWilliams's scheme (Gent and McWiiliams, 1990) for isopycnal mixing, and quicker advection scheme (Leonald, 1979). The...

NIES wind-tunnel dataset

Yukio Yamao Isao Kanda
Impact on human health by automobile air pollutants in roadside areas was investigated in the SORA (Study On Respiratory disease and Automobile exhaust) project (H17-22fy) administered by the Japan Ministry of Environment. In this project, a model was developed for estimating air-pollutant exposure to roadside residents. To provide validation data for this model, diffusion experiments under various building configurations from regular arrays to real cities were conducted in the Atmospheric Diffusion Wind Tunnel at National...

GDHY

The Global Dataset of Historical Yield (GDHY_v1_2) offers annual time series data of 0.5-degree grid-cell yield estimates of major crops worldwide. The crops considered in this dataset are maize, rice, wheat and soybean. The unit of yield data is t/ha. The grd-cell yield data were estimated using the satellite-derived crop-specific vegetation index and FAO-reported country yield statistics. Maize and rice have the data for each of two growing seasons (major/secondary). "Winter" and "spring" are used...

S14 global meteorological forcing dataset

The S14 retrospecitive meteorological forcing dataset (S14FD) offers daily data of 11 climatic variables over the globe from 1958 to 2013. The data over the sea and Antarctica are not bias-corrected (i.e., the raw data of the JRA-55 reanalysis were used), whereas those over the land are bias-corrected. Variables include daily mean 2m air temperature (tave2m, °C), daily maximum 2m air temperature (tmax2m, °C), daily minimum 2m air temperature (tmin2m, °C), daily total precipitation (precsfc,...

Ionogram at Wakkanai, Japan

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...

Improved Limb Atmospheric Spectrometer-II (ILAS-II), Version 3.0

Sugita Takafumi, Nakajima Hideaki & Yokota Tatsuya
The Improved Limb Atmospheric Spectrometer (ILAS)-II is a satellite-borne sensor that measures ozone and its related chemical species in the high-latitude stratosphere on the basis of the solar occultation technique. There are approximately 14 measurements a day for each of the hemispheres, at sunrise seen from the satellite in the Northern Hemisphere and at sunset seen from the satellite in the Southern Hemisphere. The retrieval algorithm is based on an onion-peeling method that uses a...

Manually scaled parameters of Ionogram at Wakkanai, Japan

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...

Continuous Observational Data of Atmospheric CH4 Mixing Ratios at Cape Ochi-ishi

The present data set is time series data of atmospheric methane (CH4) mixing ratios measured at Cape Ochi-ishi situated at the base of Nemuro Peninsula in eastern Hokkaido, Japan. The monitoring station is located on top of a cliff 50 m above ground at the southern tip of the cape facing the Pacific Ocean. Air is sampled from an intake placed on a tower adjacent to the observation station about 50 m above ground level,...

DIAS_Satellite_AMSR2_TB dataset

■Satellite/Sensor The Advanced Microwave Scanning Radiometer 2 (AMSR2) onboard the GCOM-W satellite is a remote sensing instrument for measuring weak microwave emission from the surface and the atmosphere of the Earth. From about 700 km above the Earth, AMSR2 will provide us highly accurate measurements of the intensity of microwave emission and scattering. The antenna of AMSR2 rotates once per 1.5 seconds and obtains data over a 1450 km swath. This conical scan mechanism enables...
