Manitoba: Annual NDVI Analysis

This study utilized the MOD13A3 monthly NDVI data at a 1-kilometer resolution and derived the annual NDVI using the MVC method. By examining the images and animations, it's noticeable that Lake Winnipeg, located north of Winnipeg, displayed significant aquatic vegetation in the years 2006, 2009, 2011, and 2022. The reasons for this phenomenon will be investigated further in the future.

Manitoba: April Precipitation Analysis

The data for April precipitation spans a continuous 113 years. There were almost no significant time trends in the first 50 years, but in the last 63 years, from 1961 to 2023, large areas showed a significant trend of reduced precipitation. This was mainly concentrated near Brandon and in the northeastern regions. However, when measuring this trend over the entire 113-year period, its significance is considerably weakened.
