NASA Short-term Prediction Research and Transition (SPoRT) Land Information System (LIS)

The long-term climatology and real-time solution is driven by the North American Land Data Assimilation System – version 2. The SPoRT-LIS consists of a 1929 x 929 grid of the Noah LSM at 0.03-deg grid spacing in the west-east, and south-north dimensions, spanning -124.925 to -67.085 deg E longitude, and 25.075 to 52.915 deg N latitude.

A climatology run was made spanning 1981-2013, then extended into real-time beginning in April of 2015. The real-time production run has continued since then to present, running in a cycled mode every 6 hours.
