1 NAFE’06 ANCILLARY DATA Rocco Panciera, Olivier Merlin and Jeffrey Walker University of Melbourne Edward Kim NASA’s Goddard Space Flight Centre Jetse Kalma University of Newcastle g

2 Overview www.nafe.unimelb.edu.au g Change to this
NO DEW DETECTED in any sampling day Addition of skin TIR temperature data on Nov 16 for validation of ASTER g

3 Vegetation Type Visual Estimation Repeated on different days
change of cover type recorded (e.g. harvest) Different observers, different days, different denominations At least 2 estimation for each individual farm - manual inspection to assign one single value within each polygon cell: either the most common one, or the one closest to Olivier maps, or the one with more similar surroundings. mixed cells left when no reasonable choice was possible. - Manual comparison between usefull dates to confirm/change mixed cell assignment and check for harvest. - if changes in time of veg cover observed (eg. harvest), multiple VEgetationType_YX created. - unify classifications that are similar and produce unique landcover legend. g

4 Soil gravimetric samples
5 samples per farm per day 243 samples total Hydraprobe calibration Soil particle analysis Top 5 cm 5 samples per day At 5 fixed locations Range of soil moisture (see graph) g

5 Surface roughness Once per farm Same locations of grav.samples g

6 Skin Temperature for ASTER
Nov 16 9.00 – AM Y2 Y9 Idea was to have a narrower time window Not much in terms of spatial patterns, as temperal variation dominates Y12 15º 40º g
