The analysis of polar clouds from AVHRR satellite data using pattern recognition techniques [PDF]

open access: yes
The cloud cover in a set of summertime and wintertime AVHRR data from the Arctic and Antarctic regions was analyzed using a pattern recognition algorithm. The data were collected by the NOAA-7 satellite on 6 to 13 Jan. and 1 to 7 Jul. 1984 between 60 deg

Doppler cooling with coherent trains of laser pulses and tunable "velocity comb"

open access: yes, 2011
We explore the possibility of decelerating and Doppler cooling of an ensemble of two-level atoms by a coherent train of short, non-overlapping laser pulses.

The albedo of snow for partially cloudy skies [PDF]

open access: yes
The input parameters of the model are atmospheric precipitable water, ozone content, turbidity, cloud optical thickness, size and shape of ice crystal of snow and surface pressure.

A Digital Archive of Northern Hemisphere Snow Cover, November 1966 through December 1980 [PDF]

open access: yes, 1982
The purpose of this article is to acquaint the research community with a new data base—a digitized archive of Northern Hemisphere snow cover. Historically, those researchers who needed snow cover data for climatic and atmospheric boundary layer studies ...

Investigating the Impact of Optical Snow Cover Data on L-Band InSAR Snow Water Equivalent Retrievals

open access: yesJournal of Remote Sensing
No single remote sensing technique can accurately measure snow water equivalent (SWE) from space for mountain hydrology applications. To address this challenge in SWE monitoring, we evaluated a multisensor approach that leverages the strengths of both ...

Evaluation of MODIS and VIIRS Cloud-Gap-Filled Snow-Cover Products for Production of an Earth Science Data Record [PDF]

open access: yes
MODerate resolution Imaging Spectroradiometer (MODIS) cryosphere products have been available since 2000 following the 1999 launch of the Terra MODIS and the 2002 launch of the Aqua MODIS and include global snow-cover extent (SCE) (swath, daily, and 8 ...

Spectral albedos of midlatitude snowpacks [PDF]

open access: yes
Spectral albedos of impure-nonhomogeneous snowpacks, typical of midlatitudes, from 400 to 2200 nm were modeled through a numerical solution of the radiative transfer equation in the two-stream approximation.

Characterization of extrasolar terrestrial planets from diurnal photometric variability

open access: yes, 2001
The detection of massive planets orbiting nearby stars has become almost routine, but current techniques are as yet unable to detect terrestrial planets with masses comparable to the Earth's.
