Introduction Instrumental records span only a tiny fraction (<107) of the Earth’s climatic history. Therefore, indirect source of climate data must be used. Subfossil pollen and plant macrofossil data derived from sediment profiles can provide quantitative information on past climate. Recognizing the relationship between pollen assemblages and climatic variables and then interpreting foss...
It will help understand the representation legality of soil temperature to explore the correlations of soil respiration with variant properties of soil temperature. Soil temperature at 10 cm depth was hourly logged through twelve months. Basing on the measured soil temperature, soil respiration at different temporal scales were calculated using empirical functions for temperate forests. On mont...
We assess the random and systematic uncertainties affecting the central England temperature (CET) record since 1878 on daily, monthly and annual time scales. The largest contribution to uncertainty in CET on all these time scales arises from areal sampling, followed for annual and monthly CET by thermometer calibration. For the daily series, random thermometer precision and screen errors are th...
Doroodzan Dam basin is one of the strategic agricultural areas in Fars province. Changes in time series of climatic parameters, especially temperature and precipitation parameters, can have a significant impact on the growth cycle of agricultural products, the status of water resources and the economy of the populations in the area. In the present study, rainfall and temperature trends were inv...
The present study is about the analysis of mean, mean maximum and mean minimum temperatures carried out on annual, seasonal and monthly time-scales examining the data from 8 meteorological stations in Istanbul for the period 1975-2006. Various spatial and statistical tools were used to display and analyze trends in temperature data. ArcGIS was used to produce the spatially distributed temperatu...
Variation in quantities such as precipitation and temperature is often assessed by detecting and characterizing trends in available meteorological data. The objective of this study was to determine the long-term trends in annual precipitation and mean annual air temperature for the state of Kentucky. Non-parametric statistical tests were applied to homogenized and (as needed) pre-whitened annua...
Soil respiration at mean annual temperature predicts annual total across vegetation types and biomes
PAR, J.lmol/m2/s x 10o o Environment. The standard environment comprised 50 'standard' weeks (-1 year), a week being defined as the period during which 58 heat units (HU) accumulate (mean annual temperature at Mount Edgecombe, 20,3°C, giving 8,3 HU/day, using a base temperature of 12, or 58 HU/wk). Mean annual photosynthetically active radiation (PAR) income at Mount Edgecombe is 7,9 Ml/mvday, ...
felled, or girdle-poisoned) and compared measured mass loss with decay class designations. Study Site The study was installed at the US Department of Energy’s Savannah River Site (Kilgo and Blake 2005), a National Environmental Research Park, located in Aiken, Barnwell, and Allendale counties in the South Carolina upper Coastal Plain (33°25 N, 81°50 W). The climate is warm temperate to subtropi...
