Overview

What is he best known for?

The fields of study he is best known for:

  • Meteorology
  • Astronomy
  • Climate change

His scientific interests lie mostly in Environmental science, Atmospheric sciences, Climatology, Troposphere and Seasonality. In his papers, Takakiyo Nakazawa integrates diverse fields, such as Environmental science, Latitude, Meteorology, Ice core, Trace gas and Laboratory flask. His study in Latitude is interdisciplinary in nature, drawing from both Climate change, Carbon dioxide in Earth's atmosphere and Southern Hemisphere.

His Meteorology research is multidisciplinary, incorporating elements of Remote sensing and Spectrum analyzer. His research in Atmospheric sciences intersects with topics in Glacial period, Atmosphere and Isotopes of oxygen. The study incorporates disciplines such as Environmental chemistry, Inversion and Ozone in addition to Troposphere.

His most cited work include:

  • CO2 surface fluxes at grid point scale estimated from a global 21 year reanalysis of atmospheric measurements (277 citations)
  • Worldwide Measurements of Atmospheric CO2 and Other Trace Gas Species Using Commercial Airlines (180 citations)
  • Latitudinal distribution of the sources and sinks of atmospheric carbon dioxide derived from surface observations and an atmospheric transport model (176 citations)

What are the main themes of his work throughout his whole career to date?

His primary areas of investigation include Environmental science, Atmospheric sciences, Climatology, Troposphere and Stratosphere. He integrates many fields in his works, including Environmental science, Meteorology, Flux, Seasonality, Latitude and Southern Hemisphere. His Atmospheric sciences research incorporates themes from Atmosphere and Biosphere.

His work on Ice core and El Niño Southern Oscillation as part of general Climatology study is frequently connected to Growth rate, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. As part of the same scientific family, Takakiyo Nakazawa usually focuses on Troposphere, concentrating on Middle latitudes and intersecting with Atmospheric circulation. His Stratosphere course of study focuses on Altitude and Isotopes of oxygen.

He most often published in these fields:

  • Environmental science (61.54%)
  • Atmospheric sciences (44.76%)
  • Climatology (31.47%)

What were the highlights of his more recent work (between 2016-2021)?

  • Atmospheric sciences (44.76%)
  • Environmental science (61.54%)
  • Stratosphere (20.98%)

In recent papers he was focusing on the following fields of study:

Takakiyo Nakazawa mainly focuses on Atmospheric sciences, Environmental science, Stratosphere, Troposphere and Ice core. Takakiyo Nakazawa focuses mostly in the field of Atmospheric sciences, narrowing it down to topics relating to Atmosphere and, in certain cases, Greenhouse gas. A majority of his Environmental science research is a blend of other scientific areas, such as Trace gas, TRACER, Mole fraction, Biosphere and Climatology.

The Stratosphere study which covers Extratropical cyclone that intersects with Trajectory. His Troposphere research is within the category of Meteorology. Takakiyo Nakazawa interconnects Cryosphere, Fractionation and Dome, Geomorphology, Ice sheet in the investigation of issues within Ice core.

Between 2016 and 2021, his most popular works were:

  • State dependence of climatic instability over the past 720,000 years from Antarctic ice cores and climate modeling (62 citations)
  • Long-term variations of the mole fraction and carbon isotope ratio of atmospheric methane observed at Ny-Ålesund, Svalbard from 1996 to 2013 (9 citations)
  • Temporal Variations of the Mole Fraction, Carbon, and Hydrogen Isotope Ratios of Atmospheric Methane in the Hudson Bay Lowlands, Canada (7 citations)

In his most recent research, the most cited papers focused on:

  • Meteorology
  • Astronomy
  • Oceanography

His primary areas of study are Environmental science, Mole fraction, Atmospheric sciences, δ13C and Chemical transport model. Throughout his Environmental science studies, Takakiyo Nakazawa incorporates elements of other sciences such as Cube, Meteorology, Air sampling, Balloon and Scope. The various areas that Takakiyo Nakazawa examines in his δ13C study include Atmosphere, Greenhouse gas and The arctic.

Takakiyo Nakazawa has researched Atmosphere in several fields, including Climatology, Secular variation, Arctic and Biosphere. His research integrates issues of Extratropical cyclone, Equator, Isotope fractionation and Upwelling in his study of Chemical transport model. His Upwelling study deals with Stratosphere intersecting with Mixing ratio.
