Surface Radiative Thermal Management.

A science-based approach to cooling that changes how surfaces interact with sunlight and heat — reducing dangerous temperatures where people live, work, farm, and store water.

The problem

Heat is accumulating at the surface.

The Earth is warming faster than at any point in human history. While reducing greenhouse gas emissions is essential, it does not remove the large amount of heat already stored in the climate system.

Much of this heat enters the atmosphere from the ground up. Dark roofs, paved surfaces, bare soil, and overheated buildings absorb sunlight during the day and release that energy back into the air as heat — raising air temperatures, increasing humidity, and intensifying heatwaves in cities and vulnerable communities.

Surface Radiative Thermal Management addresses this problem at its source: the land surface itself.

The core idea

How Cooler Surfaces Create Cooler Air

Local cooling

Less heat is absorbed and re-released into the air just above the surface, directly cooling the spaces around homes, roads, parks, markets, and shaded areas.

Regional and global impact

Less heat continues upward into the atmosphere, helping reduce heat build-up at a regional scale and, when deployed widely, contributing to lower overall global temperatures.

Earth energy flows

See how energy moves between the surface, atmosphere, and space.

The Sun delivers energy to Earth every day. Some is reflected back to space, some is absorbed by the surface, and the rest is later emitted as heat into the air and sky.

Surface Radiative Thermal Management changes how this energy behaves: it increases reflected sunlight, reduces heat absorbed into buildings and roads, and lets more thermal energy escape to space through the atmospheric window.

The video below shows how these flows work together.

The physics, made simple

From local to global

Less heat entering the atmosphere means less heat retained in the climate system.

SRTM delivers immediate local benefits, but its significance does not stop there. When cooling is applied across many surfaces, cities absorb less heat, landscapes release less thermal energy into the air, and atmospheric heating is reduced over large areas.

WHAT MAKES MEER DIFFERENT

Designed for real communities.

Passive

No electricity, refrigerants or fuel are required. MEER's cooling systems work continuously using sunlight, reflection and natural heat transfer, reducing heat without ongoing energy consumption.

Modular

Designed to be flexible and scalable—from individual homes and schools to markets, farms and entire neighbourhoods. Systems can be adapted to different climates, landscapes and community needs.

Measured

Every deployment is designed to generate evidence. We monitor temperatures, environmental conditions and real-world performance to understand what works, improve future designs and quantify cooling benefits.

Transparent

Our research is independently developed and grounded in field evidence. We publish our methods, findings and peer-reviewed research wherever appropriate, helping build confidence through scientific transparency while protecting ongoing research and intellectual property.

Why this matters

Cooling the surface cools the system.

By reducing heat where people live, work and grow food, surface cooling delivers immediate local benefits while contributing to broader climate resilience. Through scientific research, engineering and real-world deployment, MEER is building the evidence needed to scale practical cooling solutions worldwide.
