Change of the solar radiation and its causes in the Haihe River Basin and surrounding areas

Change of the solar radiation and its causes in the Haihe River Basin and surrounding areas

The temporal and spatial variations of solar radiation and the cause of the change in solar radiation have been analyzed based on meteorological data from 46 national meteorological stations and aerosol index data from TOMS over the Haihe River
Basin and surrounding areas. The results have shown that solar radiation and direct radiation significantly decreased, while scattered radiation increased during the period 1957–2008. Spatially, the decreasing trend of solar radiation was more and more
significant from low population density areas to high population density areas. The spatial distribution of increase in aerosol index is consistent with that of decrease in solar radiation. The increase in aerosols resulting from human activities
was an important reason for the decrease in solar radiation.

To analyze the characteristics of change in the net ecosystem CO2 exchange in the daytime (NEE) and to calculate the parameters related to photosynthesis and respiration in different solar radiation environments, the NEE measurements were taken
in Damxung from July to August in 2003, 2004, 2005 and 2006 using the eddy covariance technique. The diurnal relationships between NEE and photosynthetically active radiation (PAR) varied with differences in solar radiation, which was a rectangular hyperbola
form on clear days, two different concave curves on partly cloudy days and an irregular triangle form on cloudy days. The mean CO2 absorption rate showed a decreasing trend with increasing solar radiation. Therefore, on the Tibetan Plateau, the alpine
meadow ecosystem will have a higher carbon absorption potential while solar radiation decreases in the future.

(solar) radiation. A Fourier decomposition of the temperature measurements provided an estimate of the in situ thermal conductivity of the rock and was used to calculate the conductive term. The shortwave radiation term was determined on the basis
of the pyranometer measurements adjusted to account for the angle of incidence of the sun. It is shown that, throughout clear-sky periods, heat exchanges at the surface are mainly controlled by direct solar radiation during the day, and by a roughly constant outgoing
