1 GEO-CAPE Oceans: Orbit position discussion -Is the proposed 95°W position optimal or adequate? -What do we gain or lose by shifting East or West of 95°W? - We may have to move depending on HP availability. -What would be acceptable and what would be unbearable? Slides for discussion, most produced by Dirk Aurin

4 For perspective: GVA (geo-viewing angle) GZA (geostationary sensor angle) SZA (solar zenith angle)

5 Air mass fraction over the day (on Equinox) < 5 is good

6 June 95W (red dot is orbital position, yellow is solar position)

7 December 95W

8 Equinox 95W

9 Equinox at 1800 GMT -85W, -95, -105W clockwise Air mass fraction

10 Dec. Solstice at 1800 GMT -86W, -96W, -106W clockwise Air mass fraction
