  1. 1. Ground based measurements of upper atmospheric CO and H2O using microwave radiometry

    Författare :Peter Forkman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesosphere; carbon monoxide; microwaves; radiometry; remote sensing; water vapour;

    Sammanfattning : Long series of continuous measurements of middle and upper atmospheric constituents are needed to be able to understand the anthropogenic influence on the atmosphere. Phenomena like ozone depletion and the enhanced greenhouse effect are examples where the role of human activities has to be well investigated in order to make the right decisions of necessary changes in our way of life.
