Last Week in Earth Observation: October 31, 2023
Landslide risk forecasts, gaps in observing, forecasting and keeping track of weather and Canada's wildfire season.
Welcome to a new, belated edition of ‘Last Week in Earth Observation’, containing a summary of major developments in EO from last week and some exclusive analysis and insights from TerraWatch.
In this edition: Landslide risk forecasts, gaps in observing, forecasting and keeping track of weather and Canada's wildfire season.

5. Fixing Gaps in Observing, Forecasting and Keeping Track of Weather
As I was reading this detailed analysis published by CarbonBrief on how Africa’s extreme weather has killed at least 15,000 people in 2023, I couldn’t help be astounded at the state of weather observations in the continent. Read the extract below, for understanding even finding basic rainfall data is impossible, even by using satellite data.
Kimutai led a team of scientists who tried to understand how climate change influenced the likelihood and severity of these floods.
However, the researchers were unable to carry out their analysis because they were not able to find reliable rainfall data from weather stations in the region.
She adds that the researchers also tried to use satellite information in the place of weather station data. However, data obtained from different satellites did not match up, making it impossible to tell exactly how much rainfall fell during the deadly flash floods.
This should not come as a surprise for some of you, especially in the weather and climate community, or if you have read my weather deep-dive, as African extreme weather events often go “unreported” when compared to those in North America and Europe. This is primarily due to the lack of weather stations, which are crucial to not only keep weather records but also to support forecasting and early warning efforts.
There cannot be a more representative visual than the one below to convey the gaps in weather observations!
But, not having up-to-date records of weather events is not just an African problem … it is also the case in the US. Here is a figure to demonstrate the state of record-keeping in the US, from an NPR analysis.
If you are wondering why it matters … Many states and cities are building and making decisions about their infrastructure, using rainfall records that haven't been updated in decades. So, roads will be flooded, bridges will be destroyed, and other critical infrastructure will be subject to extreme weather risks.
How do we fix this? There are certainly data gaps, which can partially be fixed with satellites with roles for stratospheric balloons, ocean buoys and yes, weather stations. But, there are also data assimilation and modelling gaps, as Hurricane Otis demonstrated, where there is certainly a role for AI. We have gotten better in understanding weather, but we have got a long way to go.
The amount of attention and media coverage that weather satellites get is inversely proportional to their societal, economic and environmental impacts on Earth, especially compared with the other segments of the space industry.
My wish? To not sweep this under the rug and actively work on fixing gaps in weather, as we are expecting several billion-dollar weather events around the world, due to climate change. This topic does not get the attention it deserves!

6. Canada’s Record-Breaking Wildfire Season
It seems like Canada’s record-breaking wildfire season could finally be coming to an end. About 45.7 million acres (18.5 million hectares) have burned in 2023, according to the Canadian Interagency Forest Fire Center, as of October 18.
Several of those fire events were continuously blazing over weeks, leading to huge swaths of areas burning down. The following animation from NASA’s Fire Events Data Suite, derived from NOAA and NASA satellite data collected day and night, showing the largest Canadian fire in the database - which had burnt 1,224,938 hectares or 4,730 square miles.
Until next time,
