Our data for Soil Water Index Global (12.5km) is based on the data from Copernicus project in Europe. This page purposes to explain detailed information for the downloadable data.
Example Dataset
Please download a free example dataset and use it in you app or analysis.
URL Expiration
All downloadable URLs expire in 90 days after your order.
Frequency and Update
The frequency is daily. Also, the latest data is usually updated within 12-24 hours after the latest Copernicus data is published.
When you see your ordered data first time, you would recognize that the data does not contain the whole data. This is NOT a bug but the data creation process has not done yet. After the order, the process begins, and then the whole data becomes accessible in several hours. In every 15 minutes, the data is revised in the direction of both the future and in the past.
