RISInfluence of Absorbing Aerosols on the Inference of Solar Surface Radiation Budget and Cloud Absorption
Publisher: American Meteorological Society
Abstract: This study addresses the impact of absorbing aerosols on the retrieval of the solar surface radiation budget (SSRB) and on the inference of cloud absorption using multiple global datasets. The data pertain to the radiation ...
General Macro- and Microphysical Properties of Deep Convective Clouds as Observed by MODIS
Publisher: American Meteorological Society
Abstract: Deep convective clouds (DCCs) are an important player in the climate system. In this paper the authors use remote sensing data mainly from the Moderate Resolution Imaging Spectroradiometer (MODIS) cloud product to investigate ...
Retrieval of Optical Depth for Heavy Smoke Aerosol Plumes: Uncertainties and Sensitivities to the Optical Properties
Publisher: American Meteorological Society
Abstract: This paper is concerned with uncertainties in the Advanced Very High Resolution Radiometer (AVHRR)-based retrieval of optical depth for heavy smoke aerosol plumes generated from forest fires that occurred in Canada due to ...
A Study toward an Improved Understanding of the Relationship between Visible and Shortwave Measurements
Publisher: American Meteorological Society
Abstract: Narrowband (NB) to broadband (BB) conversion is a common practice to acquire radiation budget data from operational imagery data. This study attempts to gain further insights into the relationship between NB visible (VIS) ...
Alteration of Atmospheric Solar Absorption by Clouds: Simulation and Observation
Publisher: American Meteorological Society
Abstract: This study investigated theoretically and experimentally two parameters employed in recent attempts to address cloud absorption anomaly. One is the ratio, R, of shortwave cloud radiative forcing (CRF) at the surface to ...
Use of ScaRaB Measurements for Validating a GOES-Based TOA Radiation Product
Publisher: American Meteorological Society
Abstract: Lack of calibrated radiation measurements at the top of the atmosphere (TOA) between major spaceborne radiation missions entails inference of the TOA radiation budget from operational weather sensors. The inferred data are ...
Quantifying Uncertainties in Determining SW Cloud Radiative Forcing and Cloud Absorption due to Variability in Atmospheric Conditions
Publisher: American Meteorological Society
Abstract: The concept of cloud radiative forcing (CRF) has been widely employed in studying the effects of clouds on the earth?s radiation budget and climate. CRF denotes, in principle, the net influence of cloud alone on the radiation ...
Improved Simulation of Clear-Sky Shortwave Radiative Transfer in the CCC-GCM
Publisher: American Meteorological Society
Abstract: The disposition of mean July clear-sky solar radiation in the Canadian Climate Centre second-generation general circulation model (CCC-GCMII) was analyzed by comparing top of the atmosphere (TOA) net fluxes with earth ...
Narrowband to Broadband Conversion with Spatially Autocorrelated Reflectance Measurements
Publisher: American Meteorological Society
Abstract: A new technique for estimating broadband reflectance from Advanced Very High-Resolution Radiometer (AVHRR) narrowband reflectances in channel 1 and 2 is developed. The data used are simultaneous and coincident narrowband ...
A Near-Global Climatology of Single-Layer and Overlapped Clouds and Their Optical Properties Retrieved from Terra/MODIS Data Using a New Algorithm
Publisher: American Meteorological Society
Abstract: Cloud overlapping has been a major issue in climate studies owing to a lack of reliable information available over both oceans and land. This study presents the first near-global retrieval and analysis of single-layer and ...
