What factors contribute to the increasing temperature of the Earth's surface?4 answersThe increasing temperature of the Earth's surface is influenced by multiple factors. Anthropogenic activities, such as the concentration of carbon dioxide in the atmosphere, have a significant impact on global surface temperature (GST). The gradual increase in black surfaces, caused by man-made activities, also contributes to the rise in surface temperature. Additionally, the greenhouse effect, resulting from increased atmospheric concentrations of greenhouse gases like carbon dioxide and methane, enhances surface warming. Furthermore, regional expressions of climate feedbacks, changes in atmospheric circulation, and other factors lead to variations in the magnitude and rate of warming across the planet. In urban areas, factors such as socio-economic factors and humidity play a role in increasing land surface temperature (LST).

How much temperature difference between surface temperature and air temperature.?4 answersThe temperature difference between surface temperature and air temperature varies depending on the land-surface cover and the specific conditions. In general, the temperature difference (ΔT) can range from 1 °C to 6 °C. Wetlands have an approximate ΔT of 1 °C. Forests have a ΔT of 1 ± 1 °C. Shrublands have a ΔT of 3-4 °C. Savannas have a ΔT between 3.5 °C and 5.5 °C. Grasslands have a ΔT of 1 °C in wet conditions and 3 °C in arid conditions. Deserts have a ΔT of 4-6 °C. The difference between screen temperature of the air at 2 m and land surface temperature (T2–LST) can range from -3 °C to -18 °C during the day, with larger values in summer due to limited heat transmission into the ground. At night, T2–LST is usually under 3 °C, with weak correlations to net radiation or ground flux. The yearly average temperature difference between air and soil surface can be 2.0 °C during the growing season of crops. The MODIS Land Surface Temperature (LST) tends to overestimate air temperature during the daytime, especially in nonforested areas.

What is the optimal temperature for pem?5 answersThe optimal operating temperature for a proton exchange membrane (PEM) fuel cell depends on various factors such as performance, CO tolerance, and durability. Based on the literature, the optimal temperature range for high-temperature PEM fuel cells (HT-PEMFCs) is between 160 °C and 180 °C. Within this range, there is a compromise between cell performance, CO tolerance, and durability. The low temperature end of the range is preferred depending on the feeding fuel. Operating the HT-PEMFC at temperatures above 180 °C may have less obvious effects on performance and CO tolerance, but it leads to faster degradation of cell performance. Additionally, operating the HT-PEMFC at temperatures below 160 °C may result in deformations occurring in the cell components, affecting its performance. Therefore, the temperature range of 160 °C to 180 °C is considered optimal for HT-PEMFCs, balancing performance, CO tolerance, and durability.

How does the corn and rice field soil temperature limits?5 answersThe temperature limits for corn and rice field soil vary depending on the specific conditions. In rice field soils, the temperature range for methanogenic activity is between 10 and 37°C, with hydrolysis of organic polymers being the rate-limiting step at temperatures above 10°C. However, thermophilic methanogens have been found in rice field soil, with a temperature optimum at approximately 41 and 50°C. The microbial community in anoxic rice field soil can produce CH4 over a wide temperature range up to 55°C, but at temperatures higher than 40°C, the methanogenic path changes to exclusively hydrogenotrophic methanogenesis. In corn field soils, the temperature range for plant growth and development is an important factor. Experiments have shown that soil temperature in pots can differ from the microclimate in the field, so it is important to consider this when extending results from pot experiments to the field.
