It is a common belief that higher elevations are naturally cooler. In pristine landscapes, this rule holds firm. But what about urban environments? Humanity moves vast amounts of matter and energy, sometimes fundamentally altering the thermodynamic parameters of our habitat.

🛰️ I correlated summer Land Surface Temperature (LST) data across Calgary’s neighborhoods with the Canadian Medium-Resolution Digital Elevation Model (MRDEM). The chart below illustrates the relationship between "Average Elevation" and "Average Surface Temperature" specifically for established residential communities. As observed, this relationship is notably weak, even though a slight cooling trend persists. Based on my data analysis, elevation above sea level is not a key factor in cooling the city.

Проект «Уровень-Спутник» или как мы сделали платформу для гидрологов

Как мы сделали сервис, который подбирает спутниковые снимки под уровень воды на гидропосту Всем привет. Меня зовут Александр Иннокентьев, и уже больше года мы с моим коллегой Павлом Головлевым делаем веб-инструмент для гидрологов под названием «Уровень-Спутник».

💻 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.

"... KEY INSIGHTS:
• Coastlines are highly dynamic — 57% accretion vs 42% erosion
• Strong contrasts between east-facing (Irish Sea) and south-facing (Atlantic) coasts
• Identification of critical erosion hotspots (e.g., Tramore) and accretion zones in embayments
• Coastal change is driven by a combination of wave climate, sediment availability, geology, and human activity

How hot was Calgary's neighborhood in 2025? 🛰️🌡️

I processed satellite data from last summer to see how Calgary’s communities handle the heat. It turns out that not all greenery is equal. My research shows a clear "breakpoint" where the density of vegetation actually starts to drop the surface temperature.

I’ve mapped the "Hottest" and "Coolest" communities — see where yours stands and why some "green" areas are still overheating.

To distinguish between "normal" and anomalous surface temperatures in Calgary in 2025, I applied Tukey’s method. The statistical distribution shows a negative skewness (coefficient ≈−0.59).

This highlights a critical phenomenon: the vast majority of the urban area is densely clustered in the warmer temperature range. In contrast, cool refuges (the rivers, reservoir, and dense parks) are statistically scarce, forming a long "tail" on the left side of the plot. In essence, Calgary’s baseline is shifted toward higher temperatures, making Urban Cool Islands a rare and vital resource.

I would like to remind my readers and followers that I am currently preparing a comprehensive article based on these research results. In it, I will explore the ecological and geochemical implications of this thermal distribution. Stay tuned for further updates!

Saturday Data Dive: Mapping Calgary’s Thermal Fingerprint 🛰️📊

Spent some quality time with GEE, R and Landsat-8/9 data today.

I’ve just finished processing a Median Land Surface Temperature (LST) model for Calgary, covering the entire Summer of 2025. This isn't just a single-day snapshot—it’s a robust composite of many satellite scenes, filtered to show the true intra-urban thermal zones.

Quick Takeaways:
🔹 Surface temperature in some busines area and "heat traps" peaked at over 51.3°C.
🔹 The contrast between our "Cool Islands" and "Extreme Heat Zones" is striking.
🔹 This automated workflow in R allows for a granular look at urban climate resilience that standard reports often miss.

I’m currently finalizing a full breakdown and a community-by-community analysis.
Stay tuned—the detailed article is coming soon!

Saturday Data Dive: Mapping Calgary’s Thermal Fingerprint 🛰️📊

Spent some quality time with GEE, R and Landsat-8/9 data today.

I’ve just finished processing a Median Land Surface Temperature (LST) model for Calgary, covering the entire Summer of 2025. This isn't just a single-day snapshot—it’s a robust composite of many satellite scenes, filtered to show the true intra-urban thermal zones.

Quick Takeaways:
🔹 Surface temperature in some busines area and "heat traps" peaked at over 51.3°C.
🔹 The contrast between our "Cool Islands" and "Extreme Heat Zones" is striking.
🔹 This automated workflow in R allows for a granular look at urban climate resilience that standard reports often miss.

I’m currently finalizing a full breakdown and a community-by-community analysis.
Stay tuned—the detailed article is coming soon!

I just figured out that #Sentinel2 overtook #Landsat in 2024 for the yearly amount of published scientific papers, at least according to the #OpenAlex database. #Sentinel2 is still far behind concerning the total number of papers, but it is still a remarkable achievement for #Copenicus and @esa

“When it comes to water, the world is changing faster than ever. 🌏 Now you can map it just as quickly within QGIS. Seen [in the first figure] are examples from France and the Dominican Republic, which leverage 11 years of the Landsat-Sentinel Harmonized 30-meter product, to reveal temporal river dynamics, ephemeral rivers beneath a bay, and lake terraces…”

Wie lässt sich das Wachstum von #Wälder​n messen, wenn sie für Menschen kaum zugänglich sind?

Mit jahrzehntealten #Satellitendaten und neuen KI-Methoden kann man überraschend viel aus alten Fotos berechnen. Wie sich #Sekundärwälder und #Plantagen dabei unterscheiden, erfahrt ihr im Artikel.
