Long Name: MODIS/Aqua+Terra Thermal Anomalies/Fire locations 1km V006 NRT (Vector data) distributed by LANCE FIRMS

Summary

Near real-time (NRT) Moderate Resolution Imaging Spectroradiometer (MODIS) Thermal Anomalies / Fire locations - Collection 6 processed by the Land, Atmosphere Near real-time Capability for EOS (LANCE) Fire Information for Resource Management System (FIRMS), using swath products (MOD14/MYD14) rather than the tiled MOD14A1 and MYD14A1 products. The thermal anomalies / active fire represent the center of a 1km pixel that is flagged by the MODIS MOD14/MYD14 Fire and Thermal Anomalies algorithm (Giglio 2003) as containing one or more fires within the pixel. This is the most basic fire product in which active fires and other thermal anomalies, such as volcanoes, are identified.

MCD14DL are available in the following formats: TXT, SHP, KML, WMS. These data are also provided through the LANCE FIRMS Fire Email Alerts. Please note only the TXT and SHP files contain all the attributes.

Collection 6 data replaced Collection 5 (which was discontinued at the end of 2016). See What's New in Collection 6?

Spatial Coverage: Global

Attribute fields

Attribute fields
Attribute Short Description Long Description
Latitude Latitude Center of 1km fire pixel but not necessarily the actual location of the fire as one or more fires can be detected within the 1km pixel.
Longitude Longitude Center of 1km fire pixel but not necessarily the actual location of the fire as one or more fires can be detected within the 1km pixel.
Brightness Brightness temperature 21 (Kelvin) Channel 21/22 brightness temperature of the fire pixel measured in Kelvin.
Scan Along Scan pixel size The algorithm produces 1km fire pixels but MODIS pixels get bigger toward the edge of scan. Scan and track reflect actual pixel size.
Track Along Track pixel size The algorithm produces 1km fire pixels but MODIS pixels get bigger toward the edge of scan. Scan and track reflect actual pixel size.
Acq_Date Acquisition Date Data of MODIS acquisition.
Acq_Time Acquisition Time Time of acquisition/overpass of the satellite (in UTC).
Satellite Satellite A = Aqua and T = Terra.
Confidence Confidence (0-100%) This value is based on a collection of intermediate algorithm quantities used in the detection process. It is intended to help users gauge the quality of individual hotspot/fire pixels. Confidence estimates range between 0 and 100% and are assigned one of the three fire classes (low-confidence fire, nominal-confidence fire, or high-confidence fire).
Version Version (Collection and source) Version identifies the collection (e.g. MODIS Collection 6) and source of data processing: Near Real-Time (NRT suffix added to collection) or Standard Processing (collection only).
"6.0NRT" - Collection 6 NRT processing.
"6.0" - Collection 6 Standard processing. Find out more on collections and on the differences between FIRMS data sourced from LANCE FIRMS and University of Maryland.
Bright_T31 Brightness temperature 31 (Kelvin) Channel 31 brightness temperature of the fire pixel measured in Kelvin.
FRP Fire Radiative Power (MW - megawatts) Depicts the pixel-integrated fire radiative power in MW (megawatts).

Near Real-Time vs Standard Products

Near Real-Time vs Standard Products

The MCD14DL NRT products are extracted from the Land, Atmosphere Near real-time Capability for EOS (LANCE) NRT versions of the MOD14 and MYD14 HDF files and maybe subject to geo-location errors or re-processing. The NRT fire data are replaced with data extracted from the standard MCD14ML Active Fire / Thermal Anomalies locations (vector data), as it becomes available, usually after 2 months, from the FIRMS Active Fire Download Tool, or from the University of Maryland MODIS Fire and Burned Area Products website.

LANCE processes data as soon as they are downlinked from satellites or transmitted from ground stations, generally within 30 minutes to two hours after satellite observation. Routines used to derive Level 2 products, such as fire, snow, and sea ice products, do not make use of ancillary data and therefore their codes are identical to the ones used in standard operations.

The difference between MODIS geolocation when using definitive vs. predicted attitude and ephemeris is routinely less than 100 meters. However, there are situations, particularly before and after spacecraft maneuvers and during space weather events, when the difference can increase up to several kilometers. The recommendation from EOSDIS is to utilize the standard product data which is reprocessed using the definitive attitude and ephemeris data.

Known Issues

MCD14DL are NRT products and may be subject to geo-location errors or re-processing. The MODIS NRT product uses predicted rather than the definitive attitude and ephemeris used by MCD14ML (Standard Product) Active Fire / Thermal Anomalies locations (available with a 3 month lag). The difference between the NRT and standard product versions of the product is routinely less than 100 meters, however, there are situations, particularly before and after spacecraft maneuvers and during space weather events, when the difference can increase up to several kilometers. The recommendation from EOSDIS is to utilize the standard product data which is reprocessed using the definitive attitude and ephemeris data.
