The full-spectrum correlated-k method for longwave atmospheric radiative transfer using an effective Planck function [PDF]

open access: yes, 2009
The correlated k-distribution (CKD) method is widely used in the radiative transfer schemes of atmospheric models and involves dividing the spectrum into a number of bands and then reordering the gaseous absorption coefficients within each one.

The Global Evolution of Giant Molecular Clouds II: The Role of Accretion [PDF]

open access: yes, 2011
We present virial models for the global evolution of giant molecular clouds. Focusing on the presence of an accretion flow, and accounting for the amount of mass, momentum, and energy supplied by accretion and star formation feedback, we are able to ...

An Assessment of the Role of Ice Hydrometeor-Types in WRF Bulk Microphysical Schemes in Simulating Two Heavy Rainfall Events over Southern Nigeria

open access: yesAtmosphere, 2019
The role of ice hydrometeor-types in bulk schemes available in the Weather Research and Forecasting (WRF) model has been assessed in this study to simulate two heavy rainfall events reported over the southern part of Nigeria.

Do Giant Molecular Clouds Care About the Galactic Structure? [PDF]

open access: yes, 2014
We investigate the impact of galactic environment on the properties of simulated giant molecular clouds formed in a M83-type barred spiral galaxy. Our simulation uses a rotating stellar potential to create the grand design features and resolves down to 1.

Cloud structures in M 17 SWex : Possible cloud–cloud collision [PDF]

open access: yesPublications of the Astronomical Society of Japan, 2020
Abstract Using wide-field 13CO (J = 1−0) data taken with the Nobeyama 45 m telescope, we investigate cloud structures of the infrared dark cloud complex in M 17 with Spectral Clustering for Interstellar Molecular Emission Segmentation. In total, we identified 118 clouds that include 11 large clouds with radii larger than 1 pc. The clouds

Schistosomiasis transmission at high altitude crater lakes in Western Uganda

open access: yesBMC Infectious Diseases, 2008
Background Contrary to previous reports which indicated no transmission of schistosomiasis at altitude >1,400 m above sea level in Uganda, in this study it has been established that schistosomiasis transmission can take place at an altitude range of 1487–

The Exciting Lives of Giant Molecular Clouds [PDF]

open access: yes, 2013
We present a detailed study of the evolution of GMCs in a galactic disc simulation. We follow individual GMCs (defined in our simulations by a total column density criterion), including their level of star formation, from their formation to dispersal. We

The HD(CP)2 Data Archive for Atmospheric Measurement Data

open access: yesISPRS International Journal of Geo-Information, 2016
The archiving of scientific data is a sophisticated mission in nearly all research projects. In this paper, we introduce a new online archive of atmospheric measurement data from the "High definition clouds and precipitation for advancing climate ...

Applicability of Multi-Frequency Passive Microwave Observations and Data Assimilation Methods for Improving NumericalWeather Forecasting in Niger, Africa

open access: yesRemote Sensing, 2014
The development of satellite-based forecasting systems is one of the few affordable solutions for developing regions (e.g., West Africa) that cannot afford ground-based observation networks.
