Abstract. A global vertically resolved aerosol data set covering more than 10 years of observations at 20 measurement sites distributed from 63° N to 52° S and 72° W 124° E has been achieved within the Raman polarization lidar network PollyNET. This consists portable, remote-controlled multiwavelength-polarization-Raman lidars (Polly) for automated continuous 24/7 clouds aerosols. PollyNET is an independent, voluntary, scientific network. All Polly feature a standardized instrument design...
Abstract Cities worldwide are piloting the use of solar reflective coatings on roads to mitigate Urban Heat Island (UHI). Solar pavement has been praised as simple, low-cost solution with a demonstrated ability reduce surface temperature. Less well understood is effect radiant heat, which influences human thermal exposure and comfort. We present first biometeorological observations coating investigate its performance from pedestrian perspective. Hourly transects were conducted in two Los...
Abstract Cities increasingly recognize the importance of shade to reduce heat stress and adopt urban forestry plans with ambitious canopy goals. Yet, implementation tree often faces maintenance, water use, infrastructure challenges. Understanding performance natural nonnatural is critical support active management in built environment. We conducted hourly transects Tempe, Arizona, mobile human-biometeorological station MaRTy on hot summer days quantify efficacy various types. sampled...
Regional land surface temperature (LST) maps derived from remote sensing data are most available to cities assess and respond heat. Yet, LST only captures one dimension of urban climate. This study investigates the extent which estimates a proxy for multiple climate variables at hyper-local scales (<10s meters). We compare remotely sensed (RS-LST) field simulated LST, MRT, air (AT), in neighborhood Tucson, Arizona, USA. find that ST follow different diurnal trends masked by RS-LST. also...
Urban overheating is an increasing threat to people, infrastructure, and the environment. Common heat mitigation strategies, such as green confront space limitations in current car-centric cities. In 2020, City of Phoenix, Arizona, piloted a "cool pavement" program using solar reflective pavement seal on 58 km residential streets. Comprehensive micrometeorological observations are used evaluate cooling potential based three exposure metrics-surface, air, mean radiant temperatures-across...
Climate feedbacks have been found to strongly impact the observed amplified Arctic warming. However, amplification is modeled with a wide spread which partly arises from intermodel differences of various feedbacks. To explain in warming, feedback uncertainties and their origins are investigated 13 climate models an experiment abruptly quadrupled CO<sub>2</sub>. While cloud feedback, being strongest Tropics, determine global mean effective sensitivity, we find that not responsible for warming...
As summer heat waves become the new normal worldwide, modeling human thermal exposure and comfort to assess mitigate urban overheating is crucial uphold livability in cities. We introduce PanoMRT, an open source human-biometeorological model calculate Mean Radiant Temperature (TMRT), Physiologically Equivalent (PET), Universal Thermal Climate Index (UTCI) from equirectangular 360° panoramas standard weather information (air temperature, relative humidity, wind speed). validated for hot, dry,...
Extreme heat puts tremendous stress on human health and limits people’s ability to work, travel, socialize outdoors. To mitigate in public spaces, thermal conditions must be assessed the context of exposure space use. Mean Radiant Temperature (MRT) is an integrated radiation metric that quantifies total load body a driving parameter many comfort indices. Current sensor systems measure MRT are expensive bulky (6-directional setup) or slow inaccurate (globe thermometers) do not sense This...
We introduce and demonstrate new measurement modeling techniques to fully resolve the spatial variation in shortwave longwave radiant heat transfer outdoor environment. for first time a way directly from terrestrial reflected diffuse sky components along with standard direct solar radiation using an adapted thermopile array ray-tracing validated by 6-direction net radiometer. Radiant is major component of experienced cities. It has significant variability that most easily noticed as one...
Abstract Researchers and city practitioners are paramount stakeholders in creating urban resilience but have diverse potentially competing views. To understand varying stakeholder perspectives, we conducted a systematic literature content analysis on green infrastructure (GI) reflective pavement (RP). The shows United States (US)-based science-practice disconnect written communication, hindering holistic decision-making. We identified 191 GI 93 RP impacts, categorized into co-benefits,...
