 An indicative history of green cover since the 1980’s

Map of the Month for July from Teagasc presents an interim output from a remote sensing study looking to see how often fields are bare of vegetation, due to harvesting or re-seeding. Using the Teagasc archive of satellite imagery going back to the 1980’s we can use vegetation indices to give an indication the number…

Remote Sensing of Lightning Strikes

We’ve had a few days of summer storms and lightning strikes leading to blackouts and animal deaths. If you want see where lightning is happening here and now, then real-time lightning detection has the answer. The detectors measure Very Low Frequency radio waves and triangulate bursts to locate lightning strikes. Met Eireann feeds data (from…

NDMI in the past ten years

In the latest Teagasc Map of the Month (https://www.teagasc.ie/rural-economy/rural-economy/spatial-analysis/gis-monthly-maps/) I used MODIS Terra surface reflectance data to calculate the Normalised Difference Moisture Index (NDMI) as a proxy for the spatial variation in the effect of the spring 2020 drought in Ireland. The specific measure I used was the difference in the average NDMI in May…
