LIS/OTD Gridded Lightning Climatology dataset annual update published, Atmospheric Research publication available

(a) HRFC mean annual flash rate from combined LIS and OTD, 0.5° grid. (b) LRFC mean annual flash rate from combined LIS and OTD, 2.5° grid.

The Global Hydrology Resource Center (GHRC) DAAC has published the annual update to the suite of LIS/OTD Gridded Lightning Climatology data sets. The annual update includes an additional year of data added to all of the data sets and a new version number (V2.3.2014) in all of the file names. These ten data sets offer full, annual, monthly and diurnal climatologies of lightning observed from space from May 1995 through December 2013, including both Optical Transient Detector and TRMM Lightning Imaging Sensor, at 0.5 and 2.5 degree resolutions. Both the LIS and the OTD instruments were developed by MSFC.

The publication describing these products and the method used to generate them was published in the journal Atmospheric Research. It is available (open access) at doi:10.1016/j.atmosres.2012.06.028.
