| LST {plotKML} | R Documentation |
LST contains a spatial sub-sample (Istra region in Croatia) of 46 time series of MODIS LST images (estimated Land Surface Temperature in degrees C) at 1 km resolution. The temporal support size of these images is 8-days.
data(LST)
The LST data frame contains the following layers:
LST2008_01_018-day MODIS LST mosaick for period 2007-12-29 to 2008-01-04
LST2008_01_098-day MODIS LST mosaick for period 2008-01-05 to 2008-01-13

Time series of 46 day-time and night-time 8-day composite LST images (MOD11A2 product bands 1 and 5) was obtained from the NASA's FTP server (https://ladsweb.modaps.eosdis.nasa.gov/). The original 8-day composite images were created by patching together images from a period of ?4 days, so that the proportion of clouds can be reduced to a minimum. The "zvalue" slot in the "RasterBrick" object can be used as the dateTime column expressed as:
yyyy-mm-ddThh:mm:sszzzzzz
where T is the separator between the date and the time, and the time zone is either Z (for UTC) or zzzzzz, which represents ?hh:mm in relation to UTC.
