Welcome to Isotope Composition Experiment /Planetary Science Laboratory!

This lab is paper editor directed by Dr. Mao-Chang Liang in Research Center for Environmental Changes,
Academia Sinica, Taipei, Taiwan

The objectives of the lab are to understand the chemical and dynamical processes in the atmospheres of planets and their satellites.

We are not limited to our www.theessayclub.com own solar system. The research of the lab can be roughly divided into two categories:

  1. Earth Sciences:
    Isotopic composition of trace molecules is a useful tool for uantifying biogeochemical cycles (their sources and sinks) in both present and paleo Earth. For example, measurements of the 15N/14N and 18O/16O ratios in N2O in two major tropospheric sources, tropical rain forest soils and fertilized soils, show that 15N and 18O are depleted relative to mean tropospheric N2O. This implies that sources of heavy N2O, enriched in 15N and 18O, must be present to balance the light N2O from soils. One such source is the back flux of N2O from the stratosphere, which is enriched in heavy N2O by UV photolysis. However, these returned fluxes of heavy N2O are so large that a large oceanic N2O flux is needed to balance the heavy stratospheric N2O. Similarly, 13C/12C and 18O/16O in CO2 have been used to quantify the uptake fluxes of CO2 between ocean and land and to estimate the terrestrial gross primary production (GPP) in the photosynthesis of plants, respectively. Like N2O, back fluxes of CO2 from the stratosphere, also enriched in heavy CO2, are possible tools for better quantifying the biogeochemical cycles involving CO2.
  2. Solar and Extrasolar Planetary Sciences:
    Star formation is of general interest to scientists, because it provides insight into the formation of planetary systems and the synthesis of organic compounds, which could lead to the appearance of life. The habitable zone and the formation of rocky planets are always located at an orbital distance of <10 AU. Current technology to probe the chemical composition and physical environment in protoplanetary disks in the regions with radius <10 AU is limited. The discovery of extrasolar planets (>200 planets) now gives astronomers a means to study the chemical and physical conditions in the inner regions (<10 AU) of disks, while that the research on solar outer planets and their satellites provides important clues to the regions >10 AU.
