This function shows the information of the 'available_RGTs' function and additionally it returns the .zip (kmz files) of all laser tracks over each 91-day repeat period (revisit time). Note that the locations and times are estimates, but should be correct to within a few minutes in time and better than 100m in the predicted locations.
revisit_time_RGTs(RGT_cycle = NULL, complete_date_sequence = FALSE)either NULL or a character string specifying a single RGT (Reference Ground Track) as determined by the output of the 'available_RGTs(only_cycle_names = TRUE)' function. If NULL then all available Data will be returned.
a boolean. If TRUE a complete sequence of Dates will be returned, otherwise only the 'minimum' and 'maximum' Dates.
a list object with the available orbit files, dates and date sequence lengths
ICESat-2 was in safe-hold from June 26 through July 9, 2019. ATLAS was off during this time, so data was not collected or pointed to the reference ground track.
