1. EMIRAD Data coSMOS2 campaign

2. coSMOS2 campaign objectives Validation of SMOS SM L2 prototype processor Assimilation of root zone moisture Investigation into the effect of water interception and dew on radiometry Investigation into the effect of sun glint over vegetation on radiometry Investigation into scaling between different pixel sizes Investigation into the effect of topography on radiometry

3. instrument EMIRAD L-band radiometer (TUD) on board SERA aircraft (ARA) 1 antenna (horn) @ nadir, the other @ 40° Nadir horn has 680 m footprint for 1000 m flight altitude 40 deg horn has 714 m footprint across track and 932 m footprint along track for 1000 m flight altitude. Same calibration over lake as PLMR

5. flight patterns ASSI: assimilation over all SM stations SCAL: scaling over Krui + Merriwa catchments  36 1km spaced parallel lines @ 1830 m (1250 m resolution) WATER: dew effect only GLINT: large range of sun-horn geometry

6. ASSI flight pattern  Fly over all farm sites @ 500 m  Providing data @ 300 m resolution  5km lines

7. 1 km separation grassland trees GLINT flight pattern  2 flight lines (at least 5km long) in the same azimuth as the sun’s position when the sun has an elevation of 40 degrees.  6 “dive flights” to increase obs angle range  4+4+3 lines; 7:30-10:00

8. WATER flight pattern  Initially scheduled over Ilogan + Roscommon  Flown over Cullingral + Midlothian to take profit of extended vegetation sampling  1 line flown 23 times from 5:50 AM till 10:10

10. Data processing TUD+ESA busy with OS campaign First Tb maps produced by the end of this month See poster by M. Berger @ EGU

11. ESA Data Envisat - MERIS: MERIS full resolution (300m), geolocated and calibrated TOA radiance (300m) Envisat - ASAR: Alternating Polarisation Mode Product - two coregistered images HH/VV - 30m spatial resolution Envisat AATSR: calibrated and geolocated images of brightness temperature (for the three infra-red channels) or reflectance (for the near-visible and visible channels), together with cloud and land identification CHRIS/PROBA: Mode 1 data: set of 5 images acquired under different angular views, 62 spectral bands in VIS/NIR - about 34m spatial resolution.
