SAFARI 2000 SURFACE SPECTRAL REFLECTANCE AT SUA PAN, BOTSWANA, DRY SEASON 2000Entry ID: s2k_misr_asd_refl
Abstract: The Multi-angle Imaging SpectroRadiometer (MISR) Validation team was deployed to Sua Pan, a salt playa in the Magkadigkadi region of Botswana, from August 18 to September 4, 2000, during the SAFARI 2000 Dry Season Aircraft Campaign. The experiment was designed to collect data necessary for multi-angle top-of-atmosphere radiance predictions in order to provide a vicarious calibration of the MISR ... instrument aboard the Terra satellite. Reported here are ground-based reflectance measurements collected using an Analytical Spectral Devices (ASD) spectroradiometer at Sua Pan and adjacent grassland targets. The grasslands provided large homogeneous areas for comparison of scale between ground measurements and remote sensing results.Data files contain numeric values that represent mean reflectance over space (grassland) or wavelength range (pan), stored as ASCII files, one file per site, in comma-separated-value (.csv) format, with column headers. The Sua Pan data, collected over a 1 km x 2 km area, are presented as rows of mean reflectance (every 10 nm) for 20 points, where the mean represents the average local reflectance spectra collected within 150 m of the given latitude and longitude. The grassland data cover a 1 km2 area and are provided every nm from 1 to 2500. Each row of data contains a mean and standard deviation at a given wavelength, where the mean represents the average of 570 measurements taken over the 1 km2 area.Related data sets from Sua Pan provide ground measurements of BRDF, and LAI and FPAR (Helmlinger et al., 2004 and Buermann and Helmlinger, 2004, respectively).

Quality The transects that were used for the amphipods were calculated by GPS for the beginning and end of each transect. The intermediate points were measured on the ground by tape measure, (every four meters) and plotted manually on the computer. Eastings and Northings for the intermediates were calculated on-screen.
All other points were gathered using GPS in the field.

Variations to work plan or objectives
Changes have been made to the sampling Methodology. Some techniques that were thought to be useful to sample from the field were discarded after a few attempts.
- Collecting invertebrates underside of stones with a modified aspirator and by hand collections was highly time consuming and no animals were found.
- The modified Berlese Funnel technique, to extract animals from dry moss sample was inappropriate for the Antarctic meiofauna and little to no yield was achieved.
- Net water samples were added to the original methodology, 35 micro-metre mesh size net was used and content drained into 50ml tube.
Soil core samples and moss samples were collected as originally proposed, adding to this, algae samples, net water samples and scraping samples from rocks, springs, and other saturated soil regions.
