GRDI is built from sociodemographic and satellite data inputs that were spatially harmonized, indexed, and weighted into six main components to produce the final GRDI layer. Inputs were selected from the best-available data that either continuously vary across space or have at least administrative level 1 (provincial/state) resolution, and which have global spatial coverage. GRDI has six input components, or dimensions, that are combined to determine the degree of relative deprivation: - **Ratio of Built-up Area to Non-built up Area (BUILT)** Evidence suggests that global rural populations are more likely to experience a higher degree of multidimensional poverty when compared to urban populations, other things being equal. Therefore, **the ratio of built-up area to non-built up area (BUILT)** is a dimension where low values imply higher deprivation. diff --git a/datasets/no2.data.mdx b/datasets/no2.data.mdx index 5815ec4f9..331351cff 100644 --- a/datasets/no2.data.mdx +++ b/datasets/no2.data.mdx @@ -47,7 +47,7 @@ layers: min: 'Less' max: 'More' unit: - label: Molecules NO2/cm2 + label: Molecules NO2/cm2 stops: - '#3A88BD' - '#C9E0ED' @@ -81,7 +81,7 @@ layers: min: '< -3' max: '> 3' unit: - label: Molecules NO2/cm2 + label: Molecules NO2/cm2 stops: - '#3A88BD' - '#C9E0ED' @@ -90,9 +90,8 @@ layers: - '#DD7059' --- - + - ## Description Nitrogen dioxide (NO2) is a common air pollutant primarily emitted from the burning of fossil fuels in cars and power plants. Lower to the ground, nitrogen dioxide can directly irritate the lungs and contributes to the production of particulate pollution and smog when it reacts with sunlight. During the COVID-19 pandemic, scientists have observed considerable decreases in nitrogen dioxide levels around the world. These decreases are predominantly associated with changing human behavior in response to the spread of COVID-19. As communities worldwide have implemented lockdown restrictions in an attempt to stem the spread of the virus, the reduction in human transportation activity has resulted in less NO2 being emitted into the atmosphere. These changes are particularly apparent over large urban areas and economic corridors, which typically have high levels of automobile traffic, airline flights, and other related activity. NASA has observed subsequent rebounds in nitrogen dioxide levels as the lockdown restrictions ease. Presented here is a monthly record of NO2 in the troposphere, which is the lowest layer of the atmosphere most directly affected by human activity, as measured by the [Ozone Monitoring Instrument (OMI)](https://aura.gsfc.nasa.gov/omi.html) on NASA’s Aura satellite from January 2016 through September 2023. Also included is a monthly record showing the change in tropospheric NO2 from the selected month compared to an average of tropospheric NO2 for the same month from 2015 - 2019 (for example, difference in NO2 between October 2023 vs October 2015 - 2019 average). This difference highlights changes in NO2 from a baseline time frame of 2015 - 2019, just before the COVID-19 pandemic. @@ -103,7 +102,7 @@ layers: - **Temporal Resolution:** Monthly - **Spatial Extent:** Global - **Spatial Resolution:** 0.1 degrees x 0.1 degrees - - **Data Units:** Molecules of nitrogen dioxide per square centimeter (Molecules NO2/cm2) + - **Data Units:** Molecules of nitrogen dioxide per square centimeter (Molecules NO2/cm2) - **Data Type:** Research
