Infrared radiation

What Is Infrared Radiation?

Infrared radiation (IR) is a type of electromagnetic radiation with wavelengths longer than those of visible light but shorter than microwaves. It is primarily associated with heat, as objects at any temperature above absolute zero emit infrared radiation. In the context of Data Analytics, infrared radiation itself is not a financial asset or a direct financial metric. Instead, its significance lies in its use as a foundational element within advanced data collection methods, such as Remote Sensing and Satellite Imagery, which generate valuable insights for financial analysis. These insights contribute to the growing field of Alternative Data, providing new perspectives on economic activity and market conditions.

History and Origin

The existence of infrared radiation was discovered in 1800 by British astronomer Sir William Herschel. Herschel was studying the heating effects of different colors of light by passing sunlight through a glass prism to create a spectrum. He used thermometers to measure the temperature of each color and noticed that the temperature increased from violet to red. Intrigued, he placed a thermometer just beyond the red end of the visible spectrum, in an area where no visible light was present. To his surprise, this region showed the highest temperature, indicating the presence of an invisible form of radiation that carried heat.¹²,¹¹

Herschel initially referred to these invisible rays as "calorific rays" because of their heat-producing properties.¹⁰ His experiment demonstrated that this "radiant heat" could be reflected, refracted, absorbed, and transmitted in a manner similar to visible light, providing the first concrete evidence that heat and light were related phenomena within a broader Electromagnetic Spectrum.⁹ The term "infrared" (meaning "below red") was coined later in the 1880s to describe this portion of the spectrum.⁸

Key Takeaways

• Challenges include data accuracy, privacy concerns, and the need for sophisticated Quantitative Analysis to derive actionable intelligence.

Interpreting Infrared Radiation

In a financial context, interpreting infrared radiation is not about analyzing the radiation itself, but rather the data and images derived from it. When infrared sensors, often on satellites, capture thermal signatures or other non-visible light properties, this raw data is then processed and analyzed to infer real-world activity. For example, the intensity of infrared emissions from industrial sites can be correlated with energy consumption or production levels, serving as an indirect measure of manufacturing output. Similarly, thermal imaging can track vehicle movement or population density, providing insights into commercial activity or urban development.

This interpretation relies heavily on Predictive Analytics and sophisticated algorithms that can translate raw physical measurements into meaningful Economic Indicators. Analysts use these derived insights to supplement traditional financial reporting and gain a more complete picture of a company's or region's operational status.

Hypothetical Example

Consider an investment firm specializing in global logistics and supply chain companies. Traditional methods for assessing a company's operational health involve reviewing its Financial Statements, earnings reports, and market news. However, the firm wants more granular, real-time insights.

They might subscribe to a service that utilizes satellite imagery, including infrared data, to monitor key logistical hubs, such as large shipping ports or distribution centers. For instance, increased infrared signatures from refrigerated containers or vehicles moving at night could indicate higher levels of activity outside normal business hours. If the infrared data consistently shows a significant uptick in activity at a major distribution center operated by "Global Freight Solutions Inc." over several weeks, this could suggest higher-than-anticipated shipping volumes.

This infrared-derived insight, when combined with other forms of Alternative Data, might lead the investment firm to believe that Global Freight Solutions Inc. is experiencing robust demand, potentially outperforming its competitors. This could influence their Financial Modeling and investment decisions regarding the company's stock or its industry peers.

Practical Applications

The practical applications of data derived from infrared radiation, primarily through Satellite Imagery, are expanding across various areas of finance:

• Economic Activity Monitoring: Analysts use infrared data from satellites to gauge economic activity in regions where traditional data may be scarce or unreliable. For example, patterns of night lights, which often include infrared components, can serve as proxies for GDP growth or development in emerging markets.⁷,⁶
• Environmental, Social, and Governance (ESG) Analysis: Companies and investors increasingly use satellite data to verify environmental claims or monitor compliance. Infrared measurements can help track deforestation, monitor industrial emissions, or assess the health of agricultural land, contributing to a company's environmental footprint assessment for ESG Investing and Due Diligence.⁵,⁴
• Retail and Commercial Real Estate: Infrared-enabled sensors can estimate foot traffic in shopping centers or occupancy rates in commercial buildings, providing insights into consumer behavior and property value.
• Commodities Markets: Infrared data can assist in crop yield forecasting by assessing vegetation health, or track the fill levels of oil storage tanks, impacting commodity price predictions.
• Insurance and Risk Management: Thermal imaging can be used in assessing post-disaster damage or identifying potential structural weaknesses in insured assets.

The use of such data offers a unique, often real-time perspective, enhancing the depth of Market Analysis for investors and analysts.

Limitations and Criticisms

Despite the innovative applications, data derived from infrared radiation, particularly as part of Alternative Data sets, faces several limitations and criticisms within finance. A primary concern is data accuracy and integrity. While satellite imagery can offer broad insights, the resolution and specific interpretations may not always be precise enough for detailed financial analysis, leading to potential misjudgments.³ Furthermore, the methodologies for processing and interpreting complex infrared data require specialized expertise, and a lack of transparency in these proprietary algorithms can make it difficult for investors to understand the underlying assumptions and potential biases.

Privacy concerns also arise, particularly when infrared data is used to track human activity or commercial operations, even if it's aggregated and anonymized. Regulatory bodies, such as the Federal Reserve, have acknowledged the benefits of alternative data in expanding access to credit but also highlight potential risks related to consumer protection, data privacy, and the possibility of discriminatory outcomes if not handled carefully.²,¹ Another criticism revolves around the "black box" nature of some advanced analytical models that utilize this data, making it challenging to attribute specific financial outcomes directly to the infrared-derived insights or to identify the root cause of an error. The cost of acquiring and processing such large datasets can also be substantial, potentially limiting its accessibility to smaller firms or individual investors.

Infrared Radiation vs. Alternative Data

While "infrared radiation" describes a physical phenomenon—a type of electromagnetic wave—"alternative data" is a broad category of non-traditional data sources used for financial analysis. The confusion sometimes arises because infrared radiation, or more precisely, data captured using infrared technology (such as from Satellite Imagery), is a source or component of alternative data.

Infrared Radiation: This is the underlying physical property. It's the heat signature emitted by objects, used by sensors to capture information that isn't visible to the human eye. It's a fundamental aspect of the Electromagnetic Spectrum.

Alternative Data: This refers to any data used for financial analysis that does not come from traditional sources like Financial Statements, analyst reports, or stock exchange feeds. Examples include credit card transaction data, web traffic data, social media sentiment, mobile phone location data, and crucially, satellite imagery (which often includes infrared and other spectral bands).

Therefore, infrared radiation is not interchangeable with alternative data. Instead, it is a key scientific principle and technological capability that enables the collection of certain types of alternative data, providing unique perspectives for investment professionals and those involved in Asset Management.
