OpenAQ Recent Conditions in Air Quality

Every day activities such as driving, burning coal for electricity, wildfires, running factories, even cooking and cleaning, release particles into the air. Besides being an irritant, small particles of 10, 2.5, 1 micrometers (PM10, PM2.5, PM1) or less are a health hazard since they can get deep into the respiratory system and damage the delicate tissues. The exposure of populations to high levels of small particles increases the risk of respiratory and cardiovascular illnesses. The [World Health Organization (WHO) guidelines] provide long-term and short-term exposure limits to PM10 and PM2.5: * Long-term: PM10 20 µg/m³ annual mean and PM2.5 10 µg/m³ * Short-term: PM10 50 µg/m³ 24-hour mean and PM2.5 25 µg/m³ Exposure to PM10 and PM2.5 above these limits may significantly impact human health. The [OpenAQ Recent Conditions in Air Quality] layers show the latest mass concentrations and particulate count for PM2.5, PM10, and PM1 of the stations in the OpenAQ data set with at least one value reported in the past 30 days. Source: The source information is the [OpenAQ community] which reports measured concentrations (µg/m³) and particle matter count (particles/cm³) on a global scale by aggregating station data from national networks of air quality. Update Frequency: It is updated every hour using the [Aggregated Live Feed (ALF)] methodology.

National Weather Service Ice Accumulation Forecast

This map displays the predicted ice accumulation for the next 72 hours across the contiguous United States. Data are updated hourly from the [National Digital Forecast Database (NDFD)] produced by the National Weather Service. The dataset includes incremental and cumulative precipitation data in 6-hour intervals. In the ArcGIS Online map viewer you can enable the time animation feature and select either the "Amount by Time" (incremental) layer or the "Accumulation by Time" (cumulative) layer to view a 72-hour animation of forecast precipitation. All times are reported according to your local time zone. Where is the data coming from? The [National Digital Forecast Database (NDFD)] was designed to provide access to weather forecasts in digital form from a central location. The NDFD produces forecast data of sensible weather elements. NDFD contains a seamless mosaic of digital forecasts from [National Weather Service (NWS)] field offices working in collaboration with the [National Centers for Environmental Prediction (NCEP)]. All of these organizations are under the administration of the [National Oceanic and Atmospheric Administration (NOAA)]. Source: [https://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndfd/AR.conus/VP.001-003/ds.iceaccum.bin] Where can I find other [NDFD] data? The Source data is downloaded and parsed using the [Aggregated Live Feeds methodology] to return information that can be served through ArcGIS Server as a map service or used to update Hosted Feature Services in Online or Enterprise.

AirNow Monitoring Site Data (Last 24 hours – PM2.5 only), US EPA, OAR, OAQPS

This United States Environmental Protection Agency (US EPA) feature layer represents site data, updated hourly concentrations and [Air Quality Index (AQI)] values for the last 24 hours received from each monitoring site that reports to [AirNow]. The values are for Particulate Matter (PM2.5) only. Map and forecast data are collected using federal reference or equivalent monitoring techniques or techniques approved by the state, local or tribal monitoring agencies. To maintain "real-time" maps, the data are displayed after the end of each hour. Although preliminary data quality assessments are performed, the data in [AirNow] are not fully verified and validated through the quality assurance procedures monitoring organizations used to officially submit and certify data on the [EPA Air Quality System (AQS)]. This data sharing, and centralization creates a one-stop source for real-time and forecast air quality data. The benefits include quality control, national reporting consistency, access to automated mapping methods, and data distribution to the public and other data systems. The U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration, National Park Service, tribal, state, and local agencies developed the [AirNow] system to provide the public with easy access to national air quality information. State and local agencies report the [Air Quality Index (AQI)] for cities across the US and parts of Canada and Mexico. [AirNow] data are used only to report the AQI, not to formulate or support regulation, guidance or any other EPA decision or position.

Flood Hazard (Best Available) Areas, Features

The data layer "Best Available Flood Hazard Area" ("Best Available") is the Effective with additional studies that have been reviewed and approved by the Division of Water. While this data has not yet been submitted to FEMA for inclusion in the FIRMs or NFHL (DFIRMs), this data can be used for general planning, construction, and development purposes. However, Best Available cannot be used for flood insurance determinations. The majority of local jurisdictions have options for using best available data; however typically only the FEMA floodplain limits have been adopted into the local floodplain ordinance.The floodplain data shown in the Best Available layer is generally more recent than the official FEMA NHFL data in the Effective layer. However, while the Best Available layer has been approved by the Division of Water, this data not gone through the due process standards FEMA requires for publication in the NFHL.Where a floodway analysis has been completed, an "Approximate Floodway" is included in the Best Available layer. These floodways are based on non-detailed floodplain modeling (i. e. no bridges), but otherwise meet the guidelines for development of floodways in Indiana. These floodways are acceptable for general use in determining jurisdiction for the Indiana Flood Control Act, but should be used with caution. These floodways do not meet the requirements for publication in the FIRMs or NFHL. This layer is included in the [Indiana Floodplain Information Portal] webmap application. For more information, please visit the DNR Division of Water's [Indiana Floodplain Mapping] website.

Open Space Preservation Community Rating System

This feature layer is intended to be used in conjunction with the [OSP Activity 420 for FEMA's CRS imagery layer]. This layer represents the relevant management attributes of areas that are likely eligible for Open Space Preservation (OSP) - Activity 422a credit through the Federal Emergency Management Agency’s (FEMA) [Community Rating System (CRS)]. It is intended to standardize screening-level OSP data for the U.S. and enable planners and floodplain managers across the nation to participate in the CRS program at a level that was not possible in the past due to data limitations. Ultimately, more communities participating in CRS will 1) help FEMA meet their mission to help communities prepare for, protect against, and recover from flood hazards, 2) help [The Nature Conservancy] meet their mission to make communities more resilient to flooding by conserving open space and restoring natural floodplain functions, and 3) make flood insurance more affordable for people both inside and outside of the regulatory floodplain. A tutorial on how to use this service can be found at [Assess open space to lower flood insurance cost]. Under the National Flood Insurance Program (NFIP), CRS is a voluntary program that provides flood insurance discounts to communities that take action to reduce their flood risk. The OSP activity is one of the largest point contributors and can greatly improve a CRS community’s overall score, which incentivizes nature-based solutions to reduce flood risk while also making flood insurance more affordable. The data in this image service are a modified subset of the USGS's Protected Areas Database of the United States (PAD-US). In accordance with the [2017 CRS Manual] requirements Esri removed all Federally or Tribally owned or managed lands larger than 10 acres. The National Hydrography Database (NHD) was then intersected with the remaining PADUS areas to extract all bodies of water larger than 10 acres and major rivers. The resulting vector dataset was then converted to 30 m raster and snapped to the National Land Cover Database (NCLD) Impervious Surface Estimation dataset. The final imagery layer represents the IDs of each of those PAD-US polygons.
CA_Tsunami_Hazard_Evacuation_NonEvacuation_Areas

Produced collectively by geologic hazard mapping scientists, and emergency planning specialists from the California Geological Survey, the California Governor’s Office of Emergency Services, and local agencies, organizations, and other stakeholders. The tsunami hazard evacuation areas were developed for all populated areas at risk to tsunamis in California and are based on the tsunami hazard defined in the Tsunami Inundation Maps for Emergency Planning. While the State assisted in the development of the evacuation areas, local agencies, organizations, and other stakeholders made the final determination on the location and coverage of these evacuation areas as they will be used for evacuation planning at the community level.
