1. Introduction

The Canadian Space Agency (CSA) is pleased to announce an opportunity for the Canadian solar-terrestrial science community to pursue research investigations that will advance understanding of geospace, the region of near-Earth space comprised of the thermosphere, ionosphere, and magnetosphere.

This Announcement of Opportunity (AO) is an initiative under the CSA Class Grant and Contribution (G&C) Program and is aimed at funding a number of projects that will carry out scientific investigations using space-based observations of geospace. These investigations will help advance understanding of the physical processes in geospace that generate space weather and stimulate the development of models that capture this understanding. The new knowledge and resulting model advancement will enable the creation of improved forecasting and now-casting capabilities that will contribute to increased Canadian resilience to the impacts of space weather.

With this AO, the CSA solicits proposals for projects that will use observations made by Canadian instruments currently in space to understand physical processes in geospace and to develop models of geospace. The successful 2013 launches of the Canadian Cascade, SmallSat, and Ionospheric Polar Explorer (CASSIOPE) and European Space Agency (ESA) Swarm missions have put new Canadian instrument payloads into low-Earth orbit. In order to maximize the scientific value of the data collected by these instruments, proposals are required to perform both

Proposers must demonstrate that the team has the expertise required to carry out both of these activities.

In addition, this AO is consistent with the terms and conditions of the CSA Class G&C Program to Support Research, Awareness and Learning in Space Science and Technology - Research Component.

Applicants are asked to read the following AO thoroughly before submitting their applications. This AO was prepared to help applicants complete the application process, and outlines key elements, including mandatory criteria for eligibility, details on eligible projects, and the selection process. In the event of any discrepancies between this AO and the individual funding agreements governing a project, the latter document(s) will take precedence.

2. AO Objectives

The objective of the CSA's solar-terrestrial science program is

The program is directed to generate advances in understanding that support the development of accurate and reliable space weather forecasts and now-casts as well as informing strategies to mitigate the impact of space weather. Together, these forecasts and strategies will improve the resilience of Canada's ground-, air-, and space-based infrastructure and related services to space weather impacts. The role that the current AO will play in delivering these benefits is illustrated by the figure below.

Graph description below.
Text version
  • Data from Canadian space- and ground-based observatories
  • New knowledge from analysis of space data by academia (enabled by this AO)
  • Enhanced monitoring and prediction tools (models) by government departments and academia
    • Government: Canada has more accurate and reliable forecasts and improved policies
      • Resilience to climate change and space weather (societal needs)
    • Industry: Improved engineering and operations strategies
      • Innovation and economic growth sustained

The primary objectives of this AO are:

These objectives are supported by the following secondary objectives:

Taken together, the primary objectives will support the development and application of new space-related knowledge. Both primary objectives will be realized through the use of data acquired by recently launched Canadian instruments. These data are given priority over other eligible data in order to maximize the scientific return of the Canadian instruments. The eligible data and prioritization are described below (Appendix B).

The models may be expressed in either analytical or computational form and may represent all or part of the geospace system. For the purposes of this AO, an analytical model is considered to be a set of mathematical equations that describe a system while a computational model is any model that must be run on a computer in order to describe the system. Examples of computational models include physics-based simulation models (e.g. magnetohydrodynamic models of the entire magnetosphere) and parameterized models derived from statistical analyses of data (e.g. location of the auroral oval as a function of Kp-index).

Alignment of the research with national and international science priorities serves to increase the impact of the research. The relevant documents are listed in Appendix C.
