Implementation of Electronic Crosstalk Correction to Terra PV LWIR Bands in Collection 6.1

In support of the upcoming Collection 6.1 reprocess, MCST applied a correction for the electronic crosstalk (Xtalk) contamination in the Terra MODIS photovoltaic (PV) long-wave infrared (LWIR) bands 27-30. Using scheduled lunar observations, the correction coefficients are derived and applied to the on-board calibrator (OBC) data and Earth-view (EV) data to correct the L1B calibrated radiance for bands 27-30. This results in a significant reduction in the image striping and radiometric biases in the L1B data.  A more detailed summary of this implementation is attached below.
