Anthropogenic radionuclides in atmospheric air over Switzerland during the last few decades

Investigating Temporal Trends and Spatial Characteristics of Rainfall and Meteorological Drought in the West of Iran during the Last Few Decades

Drought is one of the most serious problems arising for human societies and ecosystems from climatevariability. This phenomenon causes billions of dollars in global damages annually and affects morepeople than any other form of natural disasters.In this study, the trends of rainfall and meteorological drought time series were investigated at tenstations located in the east of Iran for the perio...

Spatial-temporal analysis of heat waves in Iran over the last three decades

The purpose of this research is to analyze heat waves characteristics in the warm period of the year as a climatic hazard in Iran. In this study, the daily maximum temperature is taken at 44 synoptic stations during the period 1981-2010. These temperature values were used to extract the intensity, frequency and duration of heat waves using percentile thresholds of 90, 95, and 98. The results sh...

Diurnal Cycle in Atmospheric Water over Switzerland

The TROpospheric WAter RAdiometer (TROWARA) is a ground-based microwave radiometer with an additional infrared channel observing atmospheric water parameters in Bern, Switzerland. TROWARA measures with nearly all-weather capability during dayand nighttime with a high temporal resolution (about 10 s). Using the almost complete data set from 2004 to 2016, we derive and discuss the diurnal cycles ...

Variability of global net sea–air CO2 fluxes over the last three decades using empirical relationships

The interannual variability of net sea–air CO2 flux for the period 1982–2007 is obtained from a diagnostic model using empirical subannual relationships between climatological CO2 partial pressure in surface seawater (pCO2SW) and sea surface temperature (SST), along with interannual changes in SST and wind speed. These optimum subannual relationships show significantly better correlation betwee...
