Summary: This study analyzed monthly variations in global temperature and wind speed using Theil-Sen's median linear regression and Mann-Kendall test from 1989 to 2021. The results showed an average increase in global temperature by 0.34 degrees C/10 a with clear increasing trends in most months. Certain regions, such as East Europe Plain and Central Siberia, experienced significant temperature increases, while others, like the East Europe Plain and North America, saw temperature decreases. The study also found that global wind speed showed slight changes, but regions across central Europe to the north of Central Asia had decreasing trends.

Summary: Podzolization is a soil-forming process that is sensitive to relief-related factors at a landscape scale. This study investigated the role of relief in conditioning podzolization occurrence on flysch slopes in the Outer Western Carpathians in southern Poland. The results showed that relief plays an important role in the development of Podzols, with landscape position, inclination, topography, and water table effects influencing the intensity and advancement of this process. The study proposed two feedback mechanisms, a positive one involving higher soil moisture and slower organic matter turnover and weathering leading to podzolization, and a negative one related to active geomorphic processes and lower soil moisture preventing podzolization occurrence.

Summary: The South American Mapping of Temperature (SAMeT) method presented in this study minimizes deficiencies associated with lack of observations by incorporating temperature corrections due to elevation or lapse rate of temperature (LRT). By combining observed temperatures, ERA5 reanalysis, and computed LRT values, SAMeT generates temperature fields with smaller errors compared to observations, making it a useful innovation for temperature mapping in the South American region.

Summary: This study characterized the daily and seasonal variations of surface temperature lapse rate and 0 degrees isotherm height on the western slope of the subtropical Andes in central Chile. Significant intra- and inter-day variations of the in-situ STLR were found, and the estimations were sensitive to the presence of gauging stations at high elevations.

Summary: The Tibetan Plateau (TP) is highly sensitive to climate change, and aerosols from neighboring regions have a significant impact on the TP environment. The interannual variability of pre-monsoon aerosols transported to the TP is more influenced by rainfall over the southern Himalayas than by near-surface wind. Rainfall reduces aerosols over the TP through wet scavenging, while wind plays a lesser role in aerosol transport. Previous studies reporting a positive correlation between wind and aerosols in the TP are actually attributed to the negative interannual correlations between wind and rainfall, and rainfall and fire events over the southern Himalayas. Future projections suggest that increased pre-monsoon rainfall in adjacent regions may mitigate aerosol transport to the TP.

Summary: This study accurately estimated the surface air temperature lapse rate (SATLR) in mainland China using the geographically weighted regression (GWR) model, and validated the model's accuracy and predictive ability. The results showed that the GWR model performed well in estimating SATLR and has potential wide application value in regions with complex terrain and climatic conditions.

Summary: The high-altitude Hindu Kush-Himalayan region and adjacent Indo-Gangetic plains are highly sensitive to climate change. This study analyzed the changes in tropospheric temperature over the past 45 years and found alarming increases in the mid-tropospheric temperature in Tibet and the Himalayas. The warming trend is believed to be a major factor contributing to the acceleration of snow cover and glacier melting in the region.

Summary: This study detected the contents of MC-LR in Microcystis aeruginosa cultures and water samples from the Huangpu River using ELISA and HPLC methods. The results showed that ELISA was a reliable and simple method for monitoring low levels of MC-LR. The concentration of MC-LR in the Huangpu River varied with the season, but remained below the WHO drinking water quality standard.

Summary: The study found that lapse rates estimated from small sample sizes or datasets with high noise or collinearity can have errors of several degrees C km(-1). Uncertainty in lapse rates can be reduced by correcting for spatial temperature gradients and restricting domains based on spatial clusters of stations. Simple linear regression was found to be more robust than multiple linear regression for lapse rate estimation.

Summary: This study found significant seasonal variations in soil processes and nutrient status under moss cover in the Indian Central Himalayas. Moss cover was found to positively impact soil physical properties and nutrient concentrations during the rainy season, while soil without moss cover exhibited higher values during the winter season. Moreover, moss cover promoted nitrogen transformation, as indicated by higher net nitrogen mineralization rates. These findings highlight the importance of mosses in maintaining ecosystem processes in temperate forests.

Summary: In this article, a novel model based on MODIS data is developed to estimate the daily 5-km NSATLR over the Tibetan Plateau (TP). The model uses digital elevation model and near-surface air temperature from MODIS data as input parameters, and combines moving window and specified criteria to estimate the pixel-based NSATLR with a 5-km spatial resolution over the TP. The accuracy of the model is evaluated by comparing it with NSATLR(in) (situ) based on meteorological data, showing good agreement in eastern TP and larger deviation in southern TP.

Summary: This study successfully modeled spatiotemporal continuous near-surface temperature lapse rate (TLR) in a mountain area using observed air temperature, MODIS land surface temperature (LST) products, land cover maps, and the ASTER digital elevation model (DEM). The sliding window method and diurnal temperature cycle (DTC) model were employed to achieve this. The results showed that MODIS LST can be used to calculate near-surface TLR, and the sliding window method effectively calculated spatially continuous TLR with a suitable window size of 15 x 15.

Summary: This study proposed an improved procedure for estimating gamma by combining sparse observations and newly released ERA5 reanalysis data, revealing the spatial heterogeneity in gamma over China and emphasizing the vital role played by vegetation covers in regulating local gamma. Furthermore, it was found that gamma in low altitude zones showed lower values but strong temporal fluctuations and contributed more to the interannual variability in gamma over China, mainly attributed to human activities.

Summary: This study estimates the altitudinal temperature lapse rate (TLR) for Uttarakhand State in Northern India using MODIS-LST and observed air temperature data. The results show that MODIS-LST estimated TLR during the day is less accurate than at night, with steeper rates in summer nights and shallower rates in winter days. The TLR varies significantly spatially and temporally among the 107 stations, with the steepest rate in summer and the shallowest rate in winter. Furthermore, the MODIS-LST estimated TLR is highly correlated with the observed air temperature, validating its performance.
