--> -->Temperature Trend
Land surface temperature (LST) is the radiative temperature of the land and is measured here using satellite observations of thermal energy emitted from the Earth's surface. LST maps developed show trends in median LST for the months of June, July, and August (JJA) from 2000-present. Locations where median JJA LST is increasing and decreasing over the period of record provides information on land use and land cover change impacts on excess heating and evaporative cooling.

Extreme Temperature Trend
Land surface temperature (LST) is the radiative temperature of the land and is measured here using satellite observations of thermal energy emitted from the Earth's surface. This map shows median LST for the months of June, July, and August (JJA) 2022 relative to the JJA median LST from 2000-2021. As such, it shows areas that have had above- and below-average LST during JJA 2022, and provides in formation about which areas are experiencing extreme heat due to climate and or land use and land cover change.

Flood Risk
Floods can be hazardous and damaging events, even in the arid environment of Jeddah in Saudi Arabia. These maps show modeled flood depth based on different frequencies of flood returns: 1 in 10 years, 1 in 100 years, 1 in 250 years, 1 in 500 years, and 1 in 1000 years. They demonstrate risks to assets, infrastructure, and ecosystems as a result of inundation during extreme precipitation events.

Precipitation
Precipitation is the primary water supply for reservoirs, streams, wetlands, and groundwater aquifers, and offsets irrigation demands for agricultural lands in Saudi Arabia. Our precipitation datasets draw on hourly weather models and observations that are summed each year to provide rainfall maps over nearly four decades.
