SEPs have assumed new importance because they are being actively studied by international Space Weather and Living with a Star (LWS) communities. Since the discovery of SEPs nearly six decades ago, tremendous progress has been made in their understanding over the recent years, thanks to the vast array of space and ground based instruments observing the SEPs and the related solar and interplanetary disturbances such as shocks, CMEs and eruptive flares. The solar, interplanetary, and heliospheric communities have been able to synthesize imaging and time-series data to obtain a detailed picture of the origin, composition, and propagation of SEPs as well as their geospace impact.

Conference Objectives
To bring together solar, interplanetary, and heliospheric communities involved in the study of coronal mass ejections (CMEs) and solar energetic particles (SEPs).

To enable better communication amongst these communities of scientists for a deeper understanding of the connection between SEPs and CMEs.

Conference Format
The conference will include four days of presentations and discussions plus one day devoted to a field trip to the Finnish Meteorological Institute in Helsinki, a well-known institute involved in all aspects of Sun-Earth connections. Each day of the conference will be devoted to a major topic that will have a tutorial lecture followed by invited and contributed papers. Invited speakers will include experienced researchers who can provide historical perspectives on the major topics of discussion. Afternoon sessions will be shorter to allow ample time for viewing posters and for informal discussions among participants. Graduate students are encouraged to give poster presentations.

Program Committee
This committee consists of international members who all do not agree on the current paradigms, but agree that convening this conference provides an opportunity to make significant progress.

Abstract Submissions:    Abstract Deadline : 06 May 2004

Submission Instructions

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. Please BOLD, but do not underline.

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 abstracts being submitted to and to obtain contact information. Please provide the following:
  1.  Title of meeting (Chapman Conference on Solar Energetic Plasmas and Particles) (VERY IMPORTANT!)
      a.  Corresponding address: Give name, affiliation, and mailing address of the author to whom all correspondence regarding this abstract should be sent.
      b.  Corresponding author's telephone number.
      c.  Corresponding author's fax number.
      d.  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 E-mail address:

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 +1-202-777-7331 or fax: +1-202-328-0566.


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:; A C Cohen (Hydrology Department, Watertown University, Watertown, MA 02172; ph. 413-789-1234; fax 413-789-1256; e-mail:

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.
