LAMOST Data Release 13 v1.0 contains LAMOST medium/low resolution observations of the sky and catalog information from 2011-10-24 to 2025-05-29. A total of 6,961 plates were observed during the low resolution sky survey, and 13,467,468 spectra were obtained, including 13,080,082 stellar spectra, 283,691 galactic spectra, and 103,695 quasar spectra; It contains 8,981,588 records of atmospheric parameter information for A/F/G/K stars, 986,068 records of M-type stars and their parameter information, 794,269 records of A-type star parameter information, 19,238 of white dwarf star information, 668 of cataclysmic variable stars, 29,114 of galaxy constellation synthesis information, and 31,030 of quasar characteristic emission line information. A total of 17,356,714 spectra in 3,404 plates were obtained through mid-resolution sky surveys, including 4,141,972 non time domain spectra and 13,214,742 time domain spectra. Medium resolution star parameter catalog information 3,958,829 rows in total, including 2,135,316 rows for non-time domain observations and 1,823,513 rows for time-domain observations.
