1. 1. Mesospheric measurements using microwave spectroscopy

   Författare :Ole Martin Christensen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water vapour; microwave spectroscopy; polar mesospheric clouds; remote sensing; mesosphere; retrieval; carbon monoxide; temperature; ozone; noctilucent clouds;

   Sammanfattning : The mesosphere is an altitude region of the atmosphere, covering altitudes between about 50 km to 100 km. Improved understanding of this area of the atmosphere offers possibilities of increasing the accuracy of weather forecast and climate models. LÄS MER

3. 2. Time series of mesospheric species measured using ground-based microwave spectrometry: Retrieval and Error estimation

   Författare :Ole Martin Christensen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water vapour; carbon monoxide; retrieval; remote sensing; mesosphere; microwave spectrometry;

   Sammanfattning : As the human emission of greenhouse gases continue to increase, the atmosphere is changing. The mesosphere region is particularly interesting as the magnitude oftemperature change in this region is expected to be larger, than in the lower layers of the atmosphere. LÄS MER
