🌳 Quantifying Calgary’s Microclimatic Imbalance: The Solid-to-Tree Ratio

To evaluate the structural heat load across Calgary's communities, I calculated the ratio of high-thermal artificial surfaces to cooling tree canopy: Solid / (Park + Forest), based on my 2025 satellite land cover model (LULC v6.0).

Why this ratio matters:
🔹 Thermal Stress Indicator: It measures how many square meters of heat-absorbing surfaces (asphalt, concrete, roofs, bare soil) exist for every square meter of tree canopy.
🔹 Spatial Inequality: While mature western neighborhoods maintain ratios between 1.5 and 4, eastern and peripheral zones reach values from 10 to over 50.
🔹 Evidence-Based Planning: It moves the discussion from generic averages to identifying exact spatial boundaries where microclimatic mitigation is most needed.

Note: The map uses a logarithmic scale.

🚀 Wow, all four Sentinel-1 #satellites are live, but apparently, their groundbreaking achievement is keeping us out with a 403 Forbidden error! 🤦‍♂️ Looks like the only thing they’re observing from space is our inability to access the webpage. 🌐🔒

🌥️ Pflanzen wachsen nicht nach Kalender. Sie wachsen nach Wetter und Standort. Doch genau das ist oft schwer messbar – vor allem bei Wolken oder schlechtem Licht. Eine ZALF-Studie zeigt jetzt: Radar-Satelliten können helfen. 🛰️

Sie erkennen wichtige Wachstumsphasen zuverlässig. Die Daten kommen von Sentinel-1 und sind regelmäßig verfügbar.

🥳
Here we go: Sentinel-1D is available operationally and data have started to accumulate over the weekend.

Easiest way to access them is via Copernicus Browser, where a filter for Sentinel-1D has been added last Friday.
https://browser.dataspace.copernicus.eu

💻 I took several completely independent datasets and "pitted" them against each other. One of the results is shown in this chart: the more "concrete" (roads, buildings, parking lots) my machine learning model identified in a community, the higher the surface temperature recorded by the thermal sensor.

🔥 The result: Data from different sources confirm one another. The difference in surface temperature between "green" and "concrete" residential areas averages 8–10°C throughout the summer. On certain days, this gap is likely even wider.

📉 This chart shows only established residential communities. If industrial zones were included, the trend would be even more dramatic. While modeling errors certainly exist, the overall physical pattern is undeniable.

Goodbye Sentinel-1A 🥲. Phase-out starting.

It’s actually good news because the new Sentinel-1D satellite is almost ready to take over and data are to start flowing from mid of this month.

The complete new Sentinel-1 constellation is expected to be in place around early July.
The resulting constellation of Sentinel-1C and 1D will have a 6-day revisit cycle as the original constellation of 1A and 1B but shifted by 1 day.

Result of a Principal Component Analysis (PCA) created from combined median composites of Sentinel-1 and Sentinel-2 imagery — somewhere in the Sudanese desert.

This PCA composite brings out contrasts between lithologies, structural domains, drainage patterns, and surface materials, highlighting features that are nearly invisible in standard RGB representations.

And yes — it also happens to look stunning.

Result of a Principal Component Analysis (PCA) based on combined median composites of Sentinel-1 and Sentinel-2 satellite imagery — somewhere in the desert of Sudan.

The PCA highlights contrasts between different lithologies, structural domains, and surface materials, revealing subtle geological features that are hard to distinguish in standard RGB composites.

And yes — it also looks simply beautiful.

My experiment with land-cover classification for Calgary using satellite imagery and with a machine-learning model trained on data from another continent.

The results turned out surprisingly good — most classes transferred almost perfectly.
The only noticeable shift was the Forest class: tree and shrub vegetation in the source region differs from Calgary’s, so the model mapped it conservatively here.

Still, the general structure of the landscape was captured very well, and community-level land-cover profiles look consistent.
