Park Falls MODIS reflectance data
data frame containing MODIS reflectances for the Park Falls, Wisconsin tall tower Ameriflux site. The data frame contains the variables:
chron object; timestamps (date and time)
the reflectance value for the red band
the reflectance value for the near infrared (NIR) band
the reflectance value for the blue band
the reflectance value for the shortwave infrade (SWIR) band
PFa_refl is part of the Park_Falls dataset. See documentation for 'Park_Falls' for further details.
These data are extracted from the Oak Ridge National Laboratory MODIS subsets for MODIS product MOD09A1.
