In this paper, we address a rain removal problem from a single image, even in the presence of heavy rain and rain streak accumulation. Our core ideas lie in the new rain image models and a novel deep learning architecture. We first modify an existing model comprising a rain streak layer and a background layer, by adding a binary map that locates rain streak regions. Second, we create a new mode...

• Background • Acid Rain & Cars • Acid Rain & Forests • Acid Rain & Health • Acid Rain & Water • Acid Rain in Europe • Acid Rain in US • Acid Rain Study The ecological effects of acid rain are most clearly seen in the aquatic, or water, environments, such as streams, lakes, and marshes. Acid rain flows to streams, lakes, and marshes after falling on forests, fields, buildings, and roads. Acid r...

The aim of this study was to determine the source apportionment of dust fall around Lake Chini, Malaysia. Samples were collected monthly between December 2012 and March 2013 at seven sampling stations located around Lake Chini. The samples were filtered to separate the dissolved and undissolved solids. The ionic compositions (NO3-, SO4(2-), Cl- and NH4+) were determined using ion chromatography...

A physico-chemical model for the accumulation of sulfur species in raindrops is developed in which account is taken of the mass transfer of SO1, 0,, NH, and CO1 into ideal raindrops containing the catalyst Fe(II1). The sulfur accumulation was calculated for the droplets as a function of fall distance. The model predicts the formation of sulfate due to the oxidation of dissolved SO2 by 0, and ca...

By employing wavelet and selected features (WSF), median merging (MM), and selected curve-fitting (SCF) techniques, the Precipitation Estimation from Remotely Sensed Imagery using an Artificial Neural Networks Cloud Classification System (PERSIANN-CCS) has been improved. The PERSIANN-CCS methodology includes the following four main steps: 1) segmentation of satellite cloud images into cloud pat...

Abstract. Mid-level stratiform precipitations during the passage of warm fronts were detailedly observed on two occasions (light and moderate rain) by a 355 nm polarization lidar water vapor Raman lidar, both equipped with waterproof transparent roof windows. The hours-long precipitation streaks shown in signal (X) volume depolarization ratio (δv) reveal some ubiquitous features microphysical p...
