Long Name: MODIS/Aqua+Terra Thermal Anomalies/Fire locations 1km V006 NRT (Vector data) distributed by LANCE FIRMS
Near real-time (NRT) Moderate Resolution Imaging Spectroradiometer (MODIS) Thermal Anomalies / Fire locations - Collection 6 processed by NASA's 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 61 data replaced Collection 6 in April 2021. Collection 5 (which was discontinued at the end of 2016).

|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. "6.1NRT" - Collection 61 NRT processing
"6.0" - Collection 6 Standard processing. "6.1" - Collection 61 Standard processing

|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).
|Type*||Inferred hot spot type||0 = presumed vegetation fire
1 = active volcano
2 = other static land source
3 = offshore

Near Real-Time vs Standard Products
The MCD14DL NRT products are extracted from NASA's 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 NASA's Earth Observing System Data and Information System (EOSDIS) is to utilize the standard product data which is reprocessed using the definitive attitude and ephemeris data.
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.
