+# 2025-12-08 NSW6: Transect NSW Site 6, Sentinel-2C and Landsat 9 dual overpass
+
+This is a report of the field data collected on 8 December 2025 at the location of Transect NSW Site 6
+to validate the satellite data of the Sentinel-2C and Landsat 9 dual overpass.
+The full collection of data is contained in the [National Spectral Database](https://www.ga.gov.au/scientific-topics/dea/dea-data-and-products/national-spectral-database).
+Satellite data can be found on [DEA maps](https://maps.dea.ga.gov.au/#share=s-i2o7JwB5gvXOQefhMmTLJaA14b0).

+Band-by-band plots of surface reflectance for field data versus each satellite.
+Satellite uncertainty error bars for each band are the standard deviation
+of pixel values over and surrounding the field site.
+Field uncertainty error bars are the standard deviation of values after
+averaging all spectra within the same satellite pixels.

+Plots of Satellite Surface Reflectance for each satellite versus Field Site Surface Reflectance on this day.
+The solid line represents the one-to-one equality between field and satellite measurements.
+The black dots are the values from all field site measurements prior to this date.
+The line of best fit is not shown, but its parameters are given in the bottom-right corner.
