We have conducted extensive surveys of electromagnetic ion cyclotron waves in the solar wind in 2019-2023 using high-cadence magnetic field data from Parker Solar Probe, STEREO A, and Wind missions. The waves are circularly polarized near the proton cyclotron frequency and appear to be left-hand or right-hand polarized in the spacecraft frame. Having built a database including thousands of wave events, we investigate the radial variations of wave properties from 0.1 to 1 AU, such as occurrence rate, wave power, and wave frequency. In addition, we study the relations between these wave properties and the solar wind ion velocity distributions, especially for the cases when left-hand and right-hand polarized waves occur closely in time or simultaneously. Our investigation improves the understanding of the evolution of ion-scale waves and provides better observational constraints to models of such wave-particle interactions in the solar wind.
