Reanalysis data applications

---

This page dedicate to help UTAH Tropical Research Group understanding the NCEP reanalysis data. 10 years data as well as seasonal mean values can be accessed through the following tool. The sounding plots are created by interpolating 2.5 X 2.5 degree with 6 hour interval data to the given location and time. The detailed description of NCEP reanalysis data can be found at NCEP webpage.
