Climatology, Carbon cycle, Carbon dioxide, Atmospheric sciences and Ice core are his primary areas of study. His Climatology study combines topics in areas such as Methane and Mixing ratio. His work investigates the relationship between Carbon cycle and topics such as δ13C that intersect with problems in Tropics, Atmospheric research, Atmosphere of Earth and La Niña.
His Carbon dioxide research includes elements of Biosphere and Greenhouse gas. His studies deal with areas such as Carbon sequestration, Ecology and Meteorology as well as Atmospheric sciences. As part of one scientific family, Roger J. Francey deals mainly with the area of Ice core, narrowing it down to issues related to the Firn, and often Isotopes of carbon.
Roger J. Francey mostly deals with Climatology, Atmospheric sciences, Carbon cycle, Carbon dioxide and Trace gas. His Climatology research incorporates themes from Firn and Paleoclimatology. His Atmospheric sciences study integrates concerns from other disciplines, such as Hydrology, Ecology, Meteorology and Carbon sink.
He interconnects Atmospheric models, Atmospheric chemistry, Isotopes of carbon, Inversion and La Niña in the investigation of issues within Carbon cycle. When carried out as part of a general Carbon dioxide research project, his work on Carbon dioxide in Earth's atmosphere is frequently linked to work in Latitude, therefore connecting diverse disciplines of study. The Ice core study combines topics in areas such as Geophysics and Holocene.
His scientific interests lie mostly in Climatology, Atmospheric sciences, Carbon cycle, Southern Hemisphere and Inversion. Roger J. Francey performs multidisciplinary study on Climatology and Ocean chemistry in his works. Roger J. Francey combines subjects such as Paragraph and Carbon dioxide in Earth's atmosphere, Carbon dioxide with his study of Atmospheric sciences.
Roger J. Francey frequently studies issues relating to Oceanography and Carbon dioxide. His studies in Carbon cycle integrate themes in fields like Sustainability, Firn, Climate policy, Greenhouse gas and Ice core. In his study, Trace gas and Atmospheric chemistry is strongly linked to Holocene, which falls under the umbrella field of Ice core.
Roger J. Francey focuses on Climatology, Carbon cycle, Inversion, Earth system science and Sustainability. His research integrates issues of Natural and Atmosphere in his study of Climatology. His work carried out in the field of Carbon cycle brings together such families of science as European Project for Ice Coring in Antarctica, Climate change, Firn, Dome and Ice core.
The study incorporates disciplines such as Climate policy, Carbon market, Carbon management and Global change in addition to Earth system science.
