Park Falls MODIS reflectance data

Description

Park Falls MODIS reflectance data

Format

data frame containing MODIS reflectances for the Park Falls, Wisconsin tall tower Ameriflux site. The data frame contains the variables:

date

chron object; timestamps (date and time)

red

the reflectance value for the red band

nir

the reflectance value for the near infrared (NIR) band

blue

the reflectance value for the blue band

swir

the reflectance value for the shortwave infrade (SWIR) band

Note

PFa_refl is part of the Park_Falls dataset. See documentation for 'Park_Falls' for further details.
