Enhancing relative humidity modelling using L2 regularization updates [PDF]

open access: yesScientific Reports
This study explores L2 regularization to mitigate overfitting in artificial neural networks (ANNs), focusing on the regularization coefficient, Lambda, and its effect on data distribution and multi-layer perceptron (MLP) performance.

Upper tropospheric humidity changes under constant relative humidity [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Theoretical derivations are given on the change of upper tropospheric humidity (UTH) in a warming climate. The considered view is that the atmosphere, which is getting moister with increasing temperatures, will retain a constant relative humidity.

Decreases in relative humidity across Australia

open access: yesEnvironmental Research Letters, 2021
How relative humidity is changing is important for our understanding of future changes in precipitation and evaporation. For example, decreases in relative humidity have the potential to increase evaporation and evapotranspiration increasing water ...

Factors controlling upper tropospheric relative humidity [PDF]

open access: yesAnnales Geophysicae, 2004
Factors controlling the distribution of relative humidity in the absence of clouds are examined, with special emphasis on relative humidity over ice (RHI) under upper tropospheric and lower stratospheric conditions.

What's the relative humidity in tropical caves?

open access: yesPLoS ONE, 2021
Relative humidity (RH) was measured at hourly intervals for approximately one year in two caves at seven stations near Playa del Carmen in Quintana Roo, Mexico. Sistema Muévelo Rico is a 1.1 km long cave with 12 entrances and almost no dark zone.

Evaporation of sulfate aerosols at low relative humidity [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Evaporation of sulfuric acid from particles can be important in the atmospheres of Earth and Venus. However, the equilibrium constant for the dissociation of H2SO4 to bisulfate ions, which is the one of the fundamental parameters controlling the ...
