Call for Papers

We invite you to participate in the 28th CALCON Technical Meeting by submitting an abstract for an oral or poster presentation.

CALCON promotes the interchange of technical data and lessons learned from programs within the remote sensing community, with emphasis toward calibration.

Technical sessions will be organized to cover a wide range of topics that address interests of the larger sensor calibration community, dependent on the number and quality of submissions received. Each session will focus on a broad theme represented in a selected group of submitted abstracts.

The topics listed below are grouped to illustrate several possible themes for potential technical sessions. However, we welcome abstracts on any topic relating to radiometric sensor calibration.

Session Topics and Themes

How Algorithm Development Affects Calibration

Processing measurement data enables derivation of results and finding relevant data trends. The algorithms used to process the data have a strong bearing on what results can be derived and the ease of dissemination. This session explores broad aspects related to data processing, both ground and on-orbit, including processing efficiency, processing large quantities of data, and algorithm implementation. Presenters are encouraged to include tying expected or modeled results to actual calibrated scenes when possible.
