Description
PM1EPHND is the Aqua Near Real Time (NRT) daily spacecraft definitive ephemeris data file in native format. This is MODIS Ancillary Data. The data collection consists of PM1 Platform Attitude Data that has been preprocessed by ECS to an internal standard supported by the ECS SDP Toolkit. This data is typically used in determining the geolocation of earth remote sensing observations.The file name format is the following:
PM1EPHND_NRT.Ayyyyddd.hhmm.vvv
where from left to right:
PM1 = PM1 (Aqua);
EPH = Spacecraft Ephemeris;
N = Native format;
D = Definitive;
A = Acquisition;
yyyy = data year,
ddd = Julian data day,
hh = data hour,
mm = data minute;
vvv = Version ID.

| Download this dataset through LANCE | HTML | Near real-time (NRT) data are available from MODAPS for certain Aqua and Terra MODIS L0, L1, L2, L2G, and L3 products. Whereas the standard MODIS forward processing acquires 2-hour L0 files for Aqua and Terra from EDOS within 7-8 hours of real time, LANCE-MODIS acquires session-based L0 files from EDOS and the end of the session is available within 10-30 minutes after real time. | Open resource |
