The Lower Humidity of Urban Areas Moderates Outdoor Heat Stress
Data scarcity of traditional observations cannot reveal whether surface temperature capture the potential for urban heat stress. This study improves the dataset with 40,000 citizen weather stations.

Ocean Waves Cause Drag Coefficient Asymmetry Within Typhoons
Observations show that, due to ocean waves, the drag coefficients for surface wind stresses have spatial asymmetry within typhoons, which should be considered in weather and climate simulations.
