Calibration for Data Observed by Airborne Hot-wire Liquid Water Content Sensor

open access: yes应用气象学报, 2021
Based on the cloud microphysical detection data of 10-sortie aircraft over southern Sichuan Basin in 2015 and 2017, the liquid water content measured by DMT (Droplet Measurement Technologies) hot-wire liquid water content sensor is examined, and abnormal

Aircraft Measurements on Properties of Aerosols over the Central and Eastern Qinghai-Tibet Plateau

open access: yes应用气象学报, 2021
The central and eastern Qinghai-Tibet Plateau is the birthplace of the Yellow River, the Yangtze River and the Lancang River. It is also a climate change sensitive area and a key ecological protection area.

Estimation of Aerosol Activation Ratio and Water Vapor Supersaturation at Cloud Base Using Aircraft Measurement

open access: yes应用气象学报, 2021
The vertical evolution of aerosol physiochemical properties significantly influence the capacity of particle water uptake at different atmospheric levels, which are important for the estimation of direct and indirect radiative impacts of aerosol. However,

Numerical Simulations of Cloud Number Concentration and Ice Nuclei Influence on Cloud Processes and Seeding Effects

open access: yesAtmosphere, 2022
Aerosols, through cloud condensation nuclei (CCN) or ice nuclei (IN), affect cloud microphysics. With increasing concentrations of aerosols, it is important to consider the impact of IN along with CCN on clouds and precipitation in numerical simulations;

Modifications of ECDSA [PDF]

open access: yes, 2003
We describe two variants of ECDSA one of which is secure, in the random oracle model, against existential forgery but suffers from the notion of duplicate signatures. The second variant is also secure against existential forgery but we argue that it is likely to possess only four natural duplicate signatures.
