Sizing snow grains using backscattered solar light


Kokhanovsky, A; Rozanov, V V; Aoki, T; Odermatt, D; Brockmann, C; Krüger, O; Bouvet, M; Drusch, M; Hori, M (2011). Sizing snow grains using backscattered solar light. International Journal of Remote Sensing, 32(22):6975-7008.

Abstract

In this article, we describe a technique to determine dry snow grain size from opti- cal observations. The method is based on analysis of the snow reflectance in the near-infrared region, in particular, the Medium Resolution Imaging Spectrometer (MERIS) band at 865 nm, which is common to many spaceborne optical sensors, is used. In addition, the algorithm is applied to the Moderate Resolution Imaging Spectroradiometer (MODIS) 1240 nm band. It is found that bands located at 1020 and 1240 nm are the most suitable for snow grain size remote-sensing applica- tions. The developed method is validated using MODIS observations over flat snow deposited on a lake ice in Hokkaido, Japan.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
