The Arctic region is projected to experience amplified warming as well strongly increasing precipitation rates. Equally important trends in the mean climate are changes interannual variability, but fluctuations highly uncertain and associated processes unknown. Here, we use various state-of-the-art global model simulations show that variability of will likely increase markedly (up 40% over 21st century), especially summer. This can be attributed increased poleward atmospheric moisture...
This paper shares an early-career perspective on potential themes for the upcoming International Association of Hydrological Sciences (IAHS) Scientific Decade (SD). opinion synthesizes six discussion sessions in western Europe identifying three that all offer a different hydrological threats world faces and could serve to direct broader community: “Tipping points thresholds hydrology,” “Intensification water cycle,” “Water services under pressure.” Additionally, four trends were...
Passive microwave (PMW) observations form the backbone of global precipitation measurements due to their relative directness retrievals compared those in visible/infrared. The NASA/JAXA Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation Measurement (GPM) missions have been central advancing satellite since TRMM was launched 1997. Prior TRMM, PMW estimates were derived primarily using from US Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave/Imager...
Abstract Commercial microwave links (CMLs) from cellular telecommunication networks can provide a valuable ‘opportunistic’ source of high-resolution space-time rainfall information, complementing traditional in-situ measurement devices (rain gauges, disdrometers) and remote sensors (weather radars, satellites). Their greatest potential lies in areas with low gauge densities lack weather often developing countries subtropical or tropical climate generally large spatial variability. Here, the...
Abstract. The Goddard Profiling algorithm (GPROF) converts radiometer observations from Global Precipitation Measurement (GPM) constellation satellites into precipitation estimates. Typically, high-quality ground-based estimates serve as reference to evaluate GPROF's performance. To provide a fair comparison, the are often spatially aligned GPROF. However, GPROF combines various sensors and channels, each associated with distinct footprint. Consequently, uncertainties related...
Abstract Applications like drought monitoring and forecasting can profit from the global near real-time availability of satellite-based precipitation estimates once their related uncertainties challenges are identified treated. To this end, study evaluates IMERG V06B Late Run product Global Precipitation Measurement mission (GPM), a multi-satellite that combines space-based radar, passive microwave (PMW), infrared (IR) data into gridded estimates. The evaluation is performed on...
Abstract Arctic precipitation is projected to increase more rapidly than the global mean in warming climates. However, warming‐induced changes variability of precipitation, which are related surface evaporation and poleward moisture transport (PMT), currently largely unknown. This study compares different quasi‐equilibrium climates simulated by a climate model (EC‐Earth) studies underlying mechanisms. Five simulations 400 years length forced with broad range CO 2 concentrations (0.25, 0.5,...
Abstract Spaceborne microwave radiometers represent an important component of the Global Precipitation Measurement (GPM) mission due to their frequent sampling rain systems. Microwave measure radiation (brightness temperatures Tb), which can be converted into precipitation estimates with appropriate assumptions. However, detecting shallow systems using spaceborne is challenging, especially over land, as weak signals are hard differentiate from those associated dry conditions. This study uses...
Accurate observations of the spatiotemporal variability precipitation are crucial for hydrological forecasts, notably over rapidly responding urban areas. This study assessed accuracy four rainfall datasets (three satellite products: IMERG-V06B, MSG-VIS, and MSG-IR; TAHMO gauges) Odaw catchment (Accra, Ghana) from Jan-2020–Jul-2022. IMERG is hardly able to capture strong spatial required flood forecasting, although its annual sums were comparable MSG-IR. MSG-IR has difficulties during wet...

Abstract A new pan-European climatological dataset was recently released that has a much higher spatiotemporal resolution than existing interpolated rain gauge datasets. This radar of hourly precipitation accumulations, European Radar Climatology (EURADCLIM) (Overeem et al.), covers most continental Europe with 2 km × and is adjusted employing data from potentially thousands government gauges. study aims to use this evaluate two important satellite-derived products over the period 2013–19 at...
The innovation of dual-polarization Doppler weather radars has improved the accuracy precipitation estimates over past decades. Retrieving hydrometeor types from radar data, however, remains challenging. In this study, we used a classification scheme wradlib to identify aloft two C-band in Netherlands. Four recent case studies, 2022 and 2023, were selected. A profiling radar, operating at Ka-band W-band an elevation angle 45 degrees, was employed as reference. First, output determine type....

One most popular methods to measure these fluxes Eddy Covariance (EC) technique; however, there are a number setbacks its application, especially remote topographically complex terrain such as higher altitudes Andes. Efforts have been made by scientific community parameterise based on other more...

However, retrieving accurate shallow estimates from remains challenging. The signal related formed close Earth’s surface is difficult distinguish dry weather, especially over land.  Despite relatively low rates that are often associated with precipitation, its persistent presence results in significant contribution total amount rainfall mid-...
