We present a grid of spherically symmetric model atmospheres for young pre-MS stars. This grid spans the parameter range and for , appropriate for low mass stars and brown dwarfs. A major improvement is the replacement of TiO and H2O line lists with the newer line list calculated by the NASA-AMES group, for TiO (about 175 million lines of 5 isotopes) and for H2O (about 350 million lines in 2 isotopes). We provide the model structures, spectra and broad-band colors in standard filters in electronic form.
