HDF and HDF-EOS data formats, software libraries and application programming interfaces (APIs), have been widely used for NASA earth observation mission data for many years. The latest version of HDF, HDF5 is the current or planned data format for missions including Orbiting Carbon Observatory 2 (OCO-2) and Joint Polar Satellite System (JPSS), totaling many 10s of terabytes of data. Users cite many strengths, including:
The TRMM Visible and Infrared Scanner (VIRS) Level 1B Calibrated Radiance Product (1B01) contains calibrated radiances and auxiliary geolocation information from the five channels of the VIRS instrument, for each pixel of each scan. The data are stored in the Hierarchical Data Format (HDF), which includes both core and product specific metadata applicable to the VIRS measurements. A file contains a single orbit of data with a file size of about 95 MB. The EOSDIS "swath" structure is used to accommodate the actual geophysical data arrays.
Lightning Imaging Sensor Background Images. These background images created approximately one to two seconds apart provide the scene on which lightning can be plotted. When using the LIS/OTD Read Software, an entire orbits worth of background images can be displayed in a simple animation to allow a quick way to see if interesting cloud systems (hurricanes, MCSs, Frontal systems, etc.) were in the field of view.
The Lightning Imaging Sensor (LIS) is an instrument on the Tropical Rainfall Measurement Mission satellite (TRMM) used to detect the distribution and variability of total lightning occurring in the Earth's tropical and subtropical regions. This information can be used for severe storm detection and analysis, and also for lightning-atmosphere interaction studies. The LIS instrument makes measurements during both day and night with high detection efficiency.
