title: The low-latitude sodium layer data from lidar observations at Hainan, China and São Paulo, Brazil

description: This is data used in “low-latitude sodium layer: comparative data from lidar observations at Hainan, China and Sao Paulo, Brazil”.Temperature data "figureS3" is from the Whole Atmosphere Community Climate Model (WACCM). WACCM is a comprehensive numerical model, spanning the range of altitude from the Earth's surface to the thermosphere. The development of WACCM is an inter-divisional collaboration that unifies certain aspects of the upper atmospheric modeling of HAO, the middle atmosphere modeling of ACOM, and the tropospheric modeling of CGD, using the NCAR Community Earth System Model (CESM) as a common numerical framework.The Climatological Tidal Model of the Thermosphere (CTMT) data were downloaded from the Clemson University website (https://globaldynamics.sites.clemson.edu/articles/ctmt.html). The following is a detailed introduction: CTMT is based on tidal temperature and wind observations made in the MLT region by SABER and TIDI on TIMED that are extended into the thermosphere using Hough Mode Extension (HME) modeling. The latter can be thought of as constraining a tidal model with observations and produces self-consistent tidal fields in temperature, neutral density, and zonal, meridional and vertical winds from pol-to-pole and from 80-400 km. A monthly tidal climatology is compiled from averaged 2002-2008 TIMED observations. CTMT accounts for contributions from solar radiation absorption in the troposphere and stratosphere, tropospheric latent heat release, and non-linear wave-wave interactions occurring in the MLT or below. It is valid for a solar radio flux of F10.7 = 110 sfu and includes the 6 (8) most important migrating and nonmigrating diurnal (semidiurnal) tidal components. As such it is suitable for driving upper atmosphere models that require self-consistent tidal fields in the MLT region as a lower boundary condition or to study the effects of tidal density variations in the re-entry region, to name just a few examples.
