Reanalysis data applications

---

This page dedicate to help UTAH Tropical Research Group understanding the ERA40 reanalysis data. 4 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 ERA40 reanalysis data can be found at ERA40 webpage.
