Land Surface Temperature
Accurate monitoring of Earth's surface temperature through satellite-derived information supports the understanding of many of our planet’s ecosystems, including physical processes that govern the three major cycles: carbon, energy and water.
Leveraging multiple earth observation datasets and innovative patented technology, Planet provides a twice-daily, global, consistent and accurate Land Surface Temperature products.
These datasets are not just numbers; It is a valuable tool for monitoring changes in cities, or understanding plant health and water availability. Also, this data plays a crucial role in assessing climate and meteorological risks by tracking temperature anomalies and shifts over time using the long archive capability.
What makes the Planet Land Surface Temperature (LST) product stand out is its unique blend of microwave and optical data, allowing the observation of temperature regardless of the cloud condition, so data can be compared consistently over time and space, providing the detailed insights needed for various applications.
Use Cases
Crop Stress Monitoring - Using LST as input in energy balanced-based evaporation models, crop stress can be detected early on and allows early intervention.
Phenology development - LST can be used as input for Growing Degree Days (check out the blog post). Growing degree days (GDD) is a weather-based indicator for assessing crop development. Crop producers use a measure of heat accumulation (temperature) to predict plant and pest development rates as the date for when a crop reaches maturity. The advantage of LST-based GDD lies in its ability to specifically monitor crop conditions, providing insights into the growth and development of crops, as opposed to relying solely on environmental conditions derived from air temperature.
Heatwave monitoring - Planet LST is able to monitor hot and dry conditions. The relationship between soil moisture and temperature indicates the severity and extent of drought conditions and the effect it has on crops, ecosystems, and the human population.

Subscriptions Access
Land Surface Temperature 20 m
LST 20 m is a beta product. This means the product is still under active development and may undergo changes to its methodology, accuracy, or availability. While the data is available for use, users should be aware that the product may have limitations or may be updated based on ongoing validation and feedback.
The area of interest for LST 20 m should correspond to a single agricultural field. If the AOI of a subscription includes multiple fields, whether they contain different crops or the same crop managed differently, the resulting LST data will not accurately reflect conditions within any specific field.
Land Surface Temperature 100 m
Land Surface Temperature 1000 m
