Convection parameterization remains at the core of large-scale atmospheric modeling. However, cloud microphysics in most convection schemes is often ignored or oversimplified. Partitioning deep convective cloud condensates into components that sediment and detrain, which is important for anvil cloud properties, is sensitive to cloud hydrometeor sedimentation as well as convective [...]

Only a few techniques measure aerosol absorption coefficients—the light absorbed by aerosols. This leaves a gap in understanding around aerosol optical properties. Simultaneous transmission/absorption photometry, or STAP, is a new method to measure absorption coefficients of stored samples of collected particles on filters in laboratory settings. STAP uses the radiation [...]

Agricultural activities, such as harvesting and tilling, can lift large amounts of soil particles into the air. Daytime surface heating leads to turbulent mixing in the lower levels of the atmosphere, which can affect the how long these particles remain in the air, known as lifetime, and how far they [...]

The dew point is the temperature to which air must be cooled at constant pressure for dew to form (or, more precisely, to reach saturation with respect to a plane of liquid water). It is a function of the air temperature and relative humidity, and it is usually calculated using [...]
