IT IS WELL KNOWN THAT DEEP CONVECTIVE SYSTEMS REACHING ABOVE THE TROPOPAUSE SO CALLED OVERSHOOTING CONVECTION PLAYS A MAJOR ROLE IN TRANSPORTING WATER VAPOR AND OTHER GAS SPECIES FROM THE TROPOSPHERE INTO THE STRATOSPHERE [SOLOMAN ET AL. 2016]. SOME OF THESE GAS SPECIES COULD MODULATE THE OZONE CONCENTRATION IN THE STRATOSPHERE AND HAVE IMPORTANT IMPACT ON THE STRATOSPHERIC CHEMISTRY GLOBAL RADIATION BUDGET AND CLIMATE CHANGE. RECENTLY ANDERSON ET AL. [2012] HAVE ARGUED THAT INCREASED STRATOSPHERIC WATER VAPOR WILL LEAD TO OZONE DESTRUCTION IN THE LOWER STRATOSPHERE OVER MID-LATITUDE AND AN INCREASED AMOUNT OF HARMFUL ULTRAVIOLET RADIATION AT THE SURFACE. HOWEVER TILL TODAY THE AMOUNT OF GASES IN THE STRATOSPHERE INTRODUCED BY OVERSHOOTING CONVECTION IS STILL NOT WELL QUANTIFIED FOR TWO MAIN REASONS: A) LACK OF GAS SPECIES OBSERVATIONS IN THE UPPER TROPOSPHERE AND LOWER STRATOSPHERE; B) UNKNOWN PROPERTIES OF OVERSHOOTING CONVECTION E.G. THE ICE MICROPHYSICS DURATION AND DETRAINMENT OF ICE PARTICLES FROM THE OVERSHOOTING CORES DUE TO DIFFICULTIES OF COLLECTING MEASUREMENTS IN THE STRONG CONVECTIVE CORES. DCOTSS PROJECT IS TO UNDERSTAND THE DYNAMICS AND CHEMISTRY OF SUMMER STRATOSPHERE OVER THE US. THE ROLE OF TEAM AT TEXAS A&M CORPUS CHRISTI (TAMUCC) IS TO FOCUS ON UNDERSTANDING THE PROPERTIES ESPECIALLY THE ICE MICROPHYSICAL PROPERTIES OF OVERSHOOTING CONVECTION OVER THE US AND THE GLOBE.
