Monitoring at Ground-based Stations

Hateruma
Hateruma Station (Quick plot、Source data (CO2, CH4, N2O) (User registration is unnecessary))
Hateruma Island, part of the Yaeyama Islands, is a small island situated 22 km south of Iriomote Island, the largest of the island group, and 50 km southwest of Ishigaki Island, which is the administrative center of Hateruma. Hateruma Island, with the Tropic of Cancer lying only approximately 66 km southwards, is the southern-most inhabited island in Japan with a surface area of 12.8 km2. The monitoring station is located on the east coast, approx. 100 m inland from the surrounding coral reef. Air is sampled at a height of 36 m on the monitoring tower.
Cape Ochiishi
Cape Ochiishi Station (Quick plot、Source data (CO2, CH4, N2O) (User registration is unnecessary))
Cape Oshiichi, situated at the base of the Nemuro Peninsula in eastern Hokkaido, is a small cape surrounded by cliffs. Most of the central inland, with Ochiishi Wetlands and the southern limit of the natural habitat of Sakai azalea, is designated as a protected natural conservation area. The monitoring station is located on the south coast of the cape on a cliff 50 m above sea level. Air is sampled at a height of 50 m on the monitoring tower.

Monitoring of Greenhouse Gases over Siberia

Siberia
Monitoring of Greenhouse Gases by Aircraft (Quick plotSource data (User registration))
Center for Global Environmental Research began sampling of the atmosphere using the aircraft in Siberia from 1993 in order to capture the long-term fluctuations of greenhouse gases in the continental interior. Also in Berezorechka, we went from 2001 on-site measurement of the vertical distribution of CO2 concentration using the aircraft.

Monitoring of Greenhouse Gases over the Pacific Ocean Using Regular Cargo Ships

In order to grasp the behavior of atmospheric greenhouse gases (GHGs) and the atmosphere-ocean CO2 flux in the Pacific region, CGER has conducted continuous monitoring since 1995 with the help of shipping companies, by installing monitoring equipment onboard regular cargo ships. Currently, monitoring of the atmosphere-ocean CO2 flux is conducted on the Japan - North America and Japan - Australia/New Zealand routes, and monitoring of the atmosphere is carried out on the Japan-Southeast Asia route.

Skaugran
The first co-operating cargo ship from March 1995 to October 1999 was M/S Skaugran, a lumber carrier of Seabord International Shipping Co., Ltd. (Canada). This ship made round-trips between Vancouver and Japan at 6-7 weeks' intervals. Two different atmosphere-ocean CO2 flux measuring instruments were installed onboard and observations were carried out by researchers onboard the cargo ship.
  • [Observation Period] 1995/03/29 - 1999/10/18
  • [Observation Point] North Pacific Ocean route (Japan - North America)
  • [Parameters] pCO2, xCO2, Air Pressure, Temperature, Humidity, Salinity, etc.

Alligator Hope
The second co-operating cargo ship from November 1999 to May 2002 was M/S Alligator Hope of Mitsui O.S.K. Lines, Ltd., a container carrier making round-trips between Japan and the U.S. and Canadian West Coast at 5 weeks’ intervals. Frequent observations of the high-latitude North Pacific area were made between Tokyo-Seattle and Vancouver-Tokyo on the 16 round-trips during the period. A fully automated measuring system, the latest at that time, was installed onboard and its operation and maintenance was contracted out to a crew member. Later on Alligator Hope changed its name to Golden Wattle and we began observations on its round-trips between Japan and Australia.
  • [Observation Period] 1999/11/12 - 2002/05/08
  • [Observation Point] North Pacific Ocean route (Japan - North America)
  • [Parameters] fCO2, pCO2, xCO2, Solar Radiation, Air Pressure, Temperature, Humidity, Wind Velocity, Salinity, etc.

Pyxis
Further observations were made from November 2001 with the co-operation of M/S Pyxis of Toyofuji Shipping Co., Ltd., a car carrier mainly operating between Toyobashi and Long Beach via Portland/Oakland, and the U.S. East Coast via the Panama Canal. However, since the monitoring equipment had become too old, observations were suspended in April 2013. We plan to resume observations from April 2014 with the co-operation of M/S New Century 2, a car carrier of Kagoshima Shipping Co., Ltd.
