This trophy is called "
Clear Skies" and it requires the user to complete the 'A Global Offensive' mission chain.
To view the chain, press the Touchpad to bring up the Character Menu. Use L1/R1 to switch to the Objectives sub-menu and L2/R2 to select Missions from it. Scroll through the missions to find "A Global Offensive" and this is where you can keep track of the chain requirements.
