CERES: Instrument Scan Modes

  

Table indicates dominant scan mode for each CERES instrument on a monthly basis.
The scan modes are cross-track XTRK, and rotating azimuth plane scan (RAPS).
XTRK is the preferred instrument for global and regional mean fluxes.

Scan mode is determined by which mode had the majority of days of operation.
