The present contribution reports on the status of the STROMA experiment. As a novelty a new experimental setup in a wind tunnel allows to simulate different stability regimes with vertical heat flux in either direction. This is accomplished upon inserting a metal sheet equipped with Peltier elements into the floor of the experimental section II of the Prof. Joaquim Blessmann wind tunnel at LAC-UFRGS (Porto Alegre, Rio Grande do Sul state, Brazil). We show results and
compare findings for two velocity magnitudes (1 Hz and 4 Hz) and with neutral and convective stability regime. Effects in the turbulent velocity field are presented with its dependence on height.
