New Technique Improves Polar Mesospheric Cloud Data Set
A new two-step Polar Mesospheric Cloud detection technique is applied towards the Himawari-8/Advanced Himawari Imager full-disk images leading to a new high-quality dataset.
Melting Layer Characteristics of Cyclones
Dual‐frequency Precipitation Radar observations reveal the characteristics and microphysical processes of the melting layer in cyclone precipitation over the western North Pacific.
Modeling Forest-Atmosphere Exchange
Studying the interactions between the atmosphere and forests is a key component of understanding forest ecosystems and the interplay between our atmosphere and the living world.
A New Way to Represent Microphysical Uncertainty
A new way of representing microphysical uncertainty in convective-scale data assimilation reduces biases in model states and improves the accuracy of short-term precipitation forecasts.
Importance of High Clouds and Moisture in Rainstorm Aggregation
A study of the impacts of radiative interactions with different cloud types on aggregation of rainstorms finds that interactions with high-clouds and water vapor are key.
AeroCom Models Improved with Aerosol and Albedo Constraints
Satellite data has been used to correct the aerosol loading and land surface albedo in several AeroCom models, which has improved shortwave flux biases between models and observations.
Uncovering Hidden Errors in Simulated Precipitation
New metrics used to quantify errors in precipitation show that convection permitting simulations outperform coarser resolution simulations.
Did the Drop in COVID-Related Emissions Affect the Climate?
Global emissions dropped markedly in 2020, due in large part to lockdowns that slowed economic and social activity, but the climate likely won’t be noticeably affected.
Making the Universe Blurrier
Climate change appears to be directly and indirectly affecting the view from at least one observatory while threatening the existence of others.
