I am trying to use this lightning data set. https://www.ncei.noaa.gov/thredds/dodsC/lightning/countPerYear_Aggregation.ncml.html i do not understand the coordiante system which was used in generating the dataset. I want to understand how to convert a simple lat, long in WGS84 into the coordinate system used to generate the dataset.

PROJCS["NAD83 / Texas Centric Albers Equal Area",

GEOGCS
["NAD83",DATUM
  ["North_American_Datum_1983",SPHEROID
  ["GRS1980",6378137,298.257222101],

How can I understand this coordinate system of this dataset?

Pasting your .prj into http://prj2epsg.org/search gives EPSG:3083, armed with that information almost any desktop gis will be able to convert your lat/lon data to that projection.
