The focus of this note is the growing applications environmental remote sensing. Satellites collect data via a number of sensor types, including optical sensors, which derive information about the Earth from reflected sunlight, and radar sensors, which transmit and receive microwave pulses to assess, for example, the texture of the surface. Advantages of remote sensing over in situ observations include:
- Remoteness–Being able to collect data from difficult-to-access regions, such as the oceans or polar regions, and at scales too large for in situ monitoring, such as at the regional, national, continental and global scales.
- Regular revisit times–Making repeated and consistent observations of the same features to monitor environmental changes. For example, changes in the extent of Arctic sea ice, forests or urban areas.
Key points in this POSTnote include:
- Earth observation (EO) data is used for many environmental applications, including weather forecasting, climate change monitoring, disaster risk reduction and biodiversity monitoring.
- EO satellites and data are part of the UK’s Space Innovation and Growth Strategy, which aims to increase the UK’s share of the global space market to 10% by 2030.
- New technologies, such as small satellites and drones, are providing new ways to access EO data.
- Government departments and the private sector are seeking to develop better ways of using EO data and services to improve efficiency and value for money.
- Challenges facing the effective us of EO data include data access and lack of EO data relevant skills. Brexit may affect the UK’s interaction with the EU EO programmes.

The use of technology to perpetrate domestic abuse, referred to as tech abuse, has become increasingly common. Domestic abuse charity Refuge reported that in 2019, 72% of women accessing its services said that they had been subjected to technology-facilitated abuse. Common devices such as smartphones and tablets can be misused to stalk, harass, impersonate and threaten victims. Some groups have raised concerns that the growing use of internet-connected home devices (such as smart speakers) may provide perpetrators with a wider and more sophisticated range of tools to harm victims. How is technology being used to perpetrate domestic abuse, how can this be prevented and what role can technology play in supporting victims?

People’s behaviour has a major role in the success of test, trace and isolate programmes. Uncertainty about whether to report symptoms, low perceived risk of COVID-19 disease and concerns about the consequences of self-isolation are among the barriers to adherence. Has the Scientific Advisory Group for Emergencies looked at adherence to TTI? What evidence is there on people’s understanding and willingness to be tested, provide contact details and self-isolate? Is there anything that can be done to improve this?
