Objectives
The purpose of the conference is to advance the understanding of atmospheric absorption with an aim of reconciling a discrepancy between models and observations. Specific objectives include:

1. A critical evaluation of basic radiative properties of the constituents of the atmosphere and surface, instrument technology, and observation methods that may have a bearing on the discrepancy; and

2. Advance hypotheses concerning the discrepancy, propose tests to resolve issues that are raised, and identify new approaches and areas that need to be investigated.

Topics

  1. Radiation Budgets of the Surface and Atmosphere
    a. clear skies and the effects of clouds
    b. broadband fluxes
    c. spectral features
  2. Optical Properties of the Atmosphere and Surface
    a. gases
    b. aerosols
    c. clouds
    d. surface
  3. Observational Methodology
    a. calibration and instrumental artifacts
    b. spectral/broadband consistency
    c. sampling problems
  4. Mechanisms for Anomalous Absorption

Abstract Submission Information

Abstract Deadline: May 10, 2001

ABSTRACT SUBMISSIONS BY E-MAIL: Compose your abstract on your E-mail software exactly as you would a normal message, using a MAXIMUM of 75 standard ASCII characters per line. Re-set your margins, if necessary, so that the text wraps from line to line, to avoid the insertion of hard returns. Follow the instructions below. A sample E-MAIL abstract is provided at the end.

I) TITLE - The title of the abstract should be composed in a standard title format, capitalizing the first letter of all words of four or more letters. Insert one blank line after title.

II) AUTHOR BLOCK- The author block should contain the name of a presenting author that should be enclosed in brackets and asterisks, like so: [*I M First*]. If there is no presenting author, then input [*---*] at the beginning of the author block. Input your author block by typing the author's name, then putting their address, phone, fax, and e-mail information in parentheses, ( ). Do not put each author on a separate line, but rather, separate each author's information with a semi-colon (;). Leave one blank line after the author block.

III) ABSTRACT TEXT - Special symbols or graphics should not be used in composing the abstract. Leave one blank line between paragraphs and after the body.

IV) SUBMITTAL INFORMATION - This section is to record information about which meeting the abstract is being submitted to and to obtain contact information. Please provide the following:
1. Title of meeting (Chapman Conference on Atmospheric Absorption of Solar Radiation) (VERY IMPORTANT!)
2. Indicate INVITED, CONTRIBUTED, or POSTER.
3a. Corresponding address: Give name, affiliation, and mailing address of the author to whom all correspondence regarding this abstract should be sent.
3b. Corresponding author's telephone number.
3c. Corresponding author's fax number 3d. Corresponding author's E-mail address.
4. Indicate whether the first author is a student.

V) SUBMIT YOUR ABSTRACT - Send the abstract to the following Internet address: asinger@agu.org

VI) CONFIRMATIONS - Confirmations of received abstracts will be sent via electronic mail within one business day of submission. If you have not received confirmation, please call the AGU at +1-202-777-7332 or fax: +1-202-328-0566, or e-mail: meetinginfo@agu.org.

SAMPLE E-MAIL ABSTRACT SUBMISSION:
Remote Sensing of Alpine Snow Properties: A Review of Techniques and Accomplishments Using the Visible Wavelengths Through the Microwave

[*J S Smith*] (Department of Geology, University of California, Santa Barbara, CA 93106-3060; ph. 805-893-2308; fax 805-893-2578; e-mail: imfirst@eos.ucsb.edu); A C Cohen (Hydrology Department, Watertown University, Watertown, MA 02172; ph. 413-789-1234; fax 413-789-1256; e-mail: ursecond@ocean.hydro.edu)

Topography causes wide variations in the properties of alpine snow within small areas, and a knowledge of the spatial variation of many properties is essential for the application of distributed hydrologic models and for establishing the surface boundary condition for regional climate models. However, the topography affects the electromagnetic remote sensing signal by shadowing some terrain and by modifying the angles of incidence, emission, and reflection of the signal, and our knowledge of the elevation model is usually not precise enough to allow a priori calculation of the geometric relationships between the surface, sensor, and the Sun. Hence remote sensing algorithms must be robust to such uncertainties, except in areas where topographic knowledge is especially good. The most elementary snow property is the presence or absence of a snow cover, and snow mapping -- discrimination of snow from other types of surfaces and from clouds -- is best accomplished with a combination of visible and near-infrared wavelengths.
