The Commission encourages:
(a) Studying all frequencies in a non-ionised environment:
(i) Studying wave propagation through planetary, neutral atmospheres and surfaces;
(ii) Studying wave interaction with the planetary atmospheres, surfaces (including land, ocean and ice), and sub surfaces;
(iii) Characterisation of the environment as it affects wave phenomena;
(b) The application of the results of these studies, particularly in the areas of remote sensing and communications;
(c) The appropriate co-operation with other URSI Commissions and other relevant organisations.
