Abstract Land surface temperature (LST) is a crucial parameter that reflects land–atmosphere interaction and has thus attracted wide interest from geoscientists. Owing to the rapid development of Earth observation technologies, remotely sensed LST playing an increasingly essential role in various fields. This review aims summarize progress estimation algorithms accelerate its further applications. Thus, we briefly most‐used thermal infrared (TIR) algorithms. More importantly, this provides comprehensive collection widely used TIR‐based products offers important insights into uncertainties these with respect different land cover conditions via systematic intercomparison analysis several representative products. In addition discussion on product accuracy, address problems related spatial discontinuity, spatiotemporal incomparability, short time span current by introducing most effective methods. With aim overcoming challenges available products, much been made developing seamless data, which significantly promotes successful applications field evapotranspiration soil moisture estimation, agriculture drought monitoring, environment anomaly climate change. Overall, encompasses recent advances state‐of‐the‐art at temporal scales, identifies critical research needs directions advance optimize retrieval methods, application improve understanding dynamics exchanges.

Climate change and human activities increasingly threaten lakes that store 87% of Earth’s liquid surface fresh water. Yet, recent trends drivers lake volume remain largely unknown globally. Here, we analyze the 1972 largest global using three decades satellite observations, climate data, hydrologic models, finding statistically significant storage declines for 53% these water bodies over period 1992–2020. The net loss in natural is attributable to warming, increasing evaporative demand, consumption, whereas sedimentation dominates losses reservoirs. We estimate roughly one-quarter world’s population resides a basin drying lake, underscoring necessity incorporating impacts into sustainable resources management.

Water availability plays a critical role in shaping terrestrial ecosystems, particularly low- and mid-latitude regions. The sensitivity of vegetation growth to precipitation strongly regulates global dynamics their responses drought, yet changes response climate change remain poorly understood. Here we use long-term satellite observations combined with dynamic statistical learning approach examine the greenness over past four decades. We observe robust increase (0.624% yr−1) for drylands, decrease (−0.618% wet Using model simulations, show that contrasting trends between dry regions are caused by elevated atmospheric CO2 (eCO2). eCO2 universally decreases reducing leaf-level transpiration, However, this transpiration reduction is overridden at canopy scale large proportional leaf area. increased drylands implies potential ecosystem stability greater impacts droughts these vulnerable ecosystems under continued change. Changes may be hydroclimate dependent. authors reveal vs. wetter last 4 decades identify as major contributing factor.

Surface water reservoirs are increasingly being relied upon to meet rising demands in the context of growing population and changing climate. However, amount available (and corresponding trends) have not been well quantified at global scale. Here we use satellite observations estimate storage variations 7245 from 1999 2018. Total reservoir has increased a rate 27.82 ± 0.08 km3/yr, which is mainly attributed construction new dams. normalized (NS)-the ratio actual capacity-has declined by 0.82 0.01%. The decline NS values especially pronounced south, while north exhibits an increase. With predicted decreasing runoff increasing demand, these observed diminishing returns will likely persist into future.

Abstract Estimates of change in global land evapotranspiration (ET) are necessary for understanding the terrestrial hydrological cycle under changing environments. However, large uncertainties still exist our estimates, mostly related to upscaling situ observations scale non-stationary surface conditions. Here, we use machine learning models, artificial neural network and random forest informed by ground atmospheric boundary layer theory, retrieve consistent long-term latent heat flux (ET energy units) sensible over recent decades. This study demonstrates that ET has increased significantly main driver is increasing temperature. Moreover, results suggest humid regions such as tropics.

Terrestrial evapotranspiration (ET) refers to a key process in the hydrological cycle by which water is transferred from Earth's surface lower atmosphere. With spatiotemporal variations, ET plays crucial role global ecosystem and affects vegetation distribution productivity, climate, resources. China features complex, diverse natural environment, leading high heterogeneity climatic variables. However, past future trends remain largely unexplored. Thus, using MOD16 products meteorological datasets, this study examined variations of 2000 2019 analyzed what behind changes, explored trends. Climate variation was statistically significant had remarkable impact on ET. Average annual increased at rate 5.3746 mm yr-1 (P < 0.01) during period. The main drivers trend are increasing precipitation wind speed. increase can also be explained some extent temperature, decreasing sunshine duration relative humidity. zonation results show that speed, decrease humidity large positive effects growth, either promoting or inhibiting different agricultural regions. Pixel-based exhibited an overall obvious spatial volatility.
