An example 1-day summary file is shown below (for display purposes I've broken the lines with a '\' character). The format of the 3-day file is identical and only the aggregation period changes.

64.76784,NA,NA,NA,NA,NAComment lines at the beginning of the file are preceeded with '# ' and include some basic site metadata along with creation and update dates and times. The number of comment lines and the metadata may change as we get more experience using these file. Dates for which there are no images (or none passing the selection criteria have empty fields as show in the second data line above. When a particular value cannot be calculated it is given a "no data" value of -9999. The last two fields are currently set to this "no data" value as we work on our algorithms for filling these flags.
The columns in the file are described below:
date: local date of middle of time period (1-day or 3-day)doy: doy for this date. The date/doy values chosen are for fixed days-of-year. image_count: number of images passing the selection criteriamidday_filename: filename for an image which is closest to noon (midday image) on the middle day of summary periodmidday_r: mean red DN over ROI for the midday imagemidday_g: mean green DN over ROI for the midday imagemidday_b: mean blue DN over ROI for thie midday imagemidday_gcc: GCC over ROI for midday imagemidday_rcc: RCC over ROi for midday imager_mean: mean value (for all images passing the selection criteria) of the mean red DN over the ROIr_std: standard deviation of red DN's for sameg_mean: mean value (for all images passing the selection criteria) of the mean green DN over the ROIg_std: standard deviation of green DN's for sameb_mean: mean value (for all images passing the selection criteria) of the mean blue DN over the ROIb_std: standard deviation of blue DN's for samegcc_mean: mean value (for all images passing the selection criteria) of the GCC over the ROIgcc_std: std. dev. of GCC for samegcc_90: 90th percentile value for GCC for samercc_mean: mean value (for all images passing the selection criteria) of the RCC over the ROIrcc_std: std. dev. of RCC for samercc_90: 90th percentile value for RCC for samemax_sza: maximum solar zenith angle for all images passing selection criteriasnow_flag: TBDoutlierflag_gcc_xx: the outlierflag, which is determined separately for the gcc_mean, gcc_50, gcc_75, and gcc_90 time series, can either take on a value of 0 (indicating good data), or 1 (indicating an outlier)The current default selection criteria is to exclude only image images with a solar zenith angle of less than 10 degrees (above horizon). The summary files are produced from the "all-image" files or ROI Timeseries so implementing your own selection criteria using the fields in that file should be straight forward.
