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...

This dataset includes data measured with induction magnetometer and electrodes that are installed at Muroto, Japan.

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,...

The AE index was proposed by Davis and Sugiura [1966] to measure a global electrojet activity in the auroral zone. It is derived from geomagnetic field variations in the H component measured at 12 stations along the auroral zone in the northern hemisphere.

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 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...

The present data set is time series data of atmospheric N2O 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, and...

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...

The spatial distribution of the data were first interpolated by near-distance interpolation method based on Baseline Meteorological Dataset of Siberia (BMDS, 77stations), and then accumulated on the annual.

This is a prototype of 0.05°(lat) x 0.05°(lon) gridded data set of spatially-interpolated daily precipitation made from station precipitation in Thailand. Most of the data are obtained from the Thai Meteorological Department (TMD) by Prof. Jun Matsumoto (Tokyo Metropolitan University/JAMSTEC). We have not taken account of topographical effects, nor systematic errors of raingauges. In our product, data are given on grid boxes over land whose altitude is below 500 m only. Furthermore, those grid boxes...

This dataset contains the daily value of the Normalize Difference Vegetation Index (NDVI) from 1982 to 2000 over the terrestrial areas of the Japan Islands that was derived from Pathfinder AVHRR Land (PAL) dataset. The horizontal resolution is 8 x 8 km. To reduce the cloud contamination, the original daily NDVI was temporally smoothed by Temporal Window Operation (TWO) method.

Three scale-types of datasets observed by new generation of remote sensing satellites (including TERRA, AQUA, ADEOS-II) in addition to TRMM and DMSP series, which were providing enhancement of observing capabilities to quantify critical atmospheric, surface, hydrologic and oceanographic data during CEOP time periods are available. 250 km square snapshots of the highest resolution raw radiances (with geographic location, i.e. level 1) remote sensing data at the 35-51 in situ reference sites are archived. ■Mission TRMM...

This dataset was created based on the daily data of 481 rainfall stations over Vietnam using the SPHEREMAP method.

This dataset includes ground information derived by visual interpretation of satellite imageries taken by Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). The dataset consists of geometries of boundaries between urban and non-urban. Although the ground information dataset is originally developed for the ASTER Global URban Area Map (AGURAM; see details at https://eco.geogrid.org/), it will be a source of training and validation for satellite remote sensing applications, such as land cover classification and urban area...

The Open-Data Inventory for Anthropogenic Carbon dioxide (ODIAC) is a high-spatial resolution global emission data product of CO2 emissions from fossil fuel combustion (Oda and Maksyutov, 2011). In 2009, the first version of ODIAC was developed by Drs. Tomohiro Oda (now at the Universities Space Research Association, USRA) and Shamil Maksyutov under the Greenhouse gases Observing SATellite (GOSAT) project at the National Institute for Environmental Studies (NIES) in Japan. ODIAC pioneered the combined use of...

The present data set is a set of daily observational data of background CO2 mixing ratios in midlatitude Asian region, measured at the summit of Mt. Fuji which is the highest mountain in Japan (3776 m a.s.l.) and located in the middle of mainland Japan. Its summit is located in the free troposphere which means it is not affected directly by air at ground level for most of the year. The daily variations of CO2...

This is a gridded data set of precipitation made from station precipitation included in the GAME Phase 2 Collected Data, by first summing up for each month at each station and then interpolating spatially.

This data set extracts glacier distribution of the Altai Mongolian area based on the topographical map(1/100,000) which the Soviet Union army created based on the aerial photograph in 1945 - 47. The extraction method performed on GIS glacier distribution indicated to the topographical map by manual work.

Kinematic GPS measurements provide in-situ data crucial for measuring the surface elevation change of glaciers. Owing to their accuracy, which is generally better than half meter, surface elevations derived from kinematic GPS surveys are useful and essential for generating precise digital elevation models (DEMs) and evaluating geometry changes of glaciers. We present a surface elevation data set derived from kinematic GPS measurements covering the lower 5 km of Qaanaaq and Bowdoin Glaciers in northwestern Greenland....

A 10-km and hourly dynamically downscaling simulation dataset from NCEP/NCAR Reanalysis over Japan for 1948-2006. The data includes most of 3-dimensional atmospheric state (temperature, wind speed, omega, height, humidity), and various surface fields (precipitation, evaporation, PBL height, surface air condition, radiation, etc.). The data is particularly useful for high resolution analysis of meteorology, and application for other fields such as agriculture or hydrology.

This dataset was created based on the daily data of 481 rainfall stations over Vietnam using the SPHEREMAP method.
