Copernicus Atmosphere Monitoring Service TEMPOral profiles (CAMS-TEMPO): global and European emission temporal profile maps for atmospheric chemistry modelling
2021
Abstract. We present the Copernicus Atmosphere Monitoring Service
TEMPOral profiles (CAMS-TEMPO), a dataset of global and European emission
temporal profiles that provides gridded monthly, daily, weekly and hourly
weight factors for atmospheric chemistry modelling. CAMS-TEMPO includes
temporal profiles for the priority air pollutants (NO x ; SO x ;
NMVOC, non-methane volatile organic compound; NH 3 ; CO; PM 10 ; and PM 2.5 ) and the greenhouse gases
(CO 2 and CH 4 ) for each of the following anthropogenic source
categories: energy industry (power plants), residential combustion,
manufacturing industry, transport (road traffic and air traffic in airports)
and agricultural activities (fertilizer use and livestock). The profiles are
computed on a global 0.1 × 0.1 ∘ and regional European 0.1 × 0.05 ∘ grid
following the domain and sector classification descriptions of the global
and regional emission inventories developed under the CAMS programme. The
profiles account for the variability of the main emission drivers of each
sector. Statistical information linked to emission variability (e.g.
electricity production and traffic counts) at national and local levels were
collected and combined with existing meteorology-dependent
parametrizations to account for the influences of sociodemographic factors
and climatological conditions. Depending on the sector and the temporal
resolution (i.e. monthly, weekly, daily and hourly) the resulting profiles are
pollutant-dependent, year-dependent (i.e. time series from 2010 to 2017)
and/or spatially dependent (i.e. the temporal weights vary per country or
region). We provide a complete description of the data and methods used to
build the CAMS-TEMPO profiles, and whenever possible, we evaluate the
representativeness of the proxies used to compute the temporal weights
against existing observational data. We find important discrepancies when
comparing the obtained temporal weights with other currently used datasets.
The CAMS-TEMPO data product including the global (CAMS-GLOB-TEMPOv2.1,
https://doi.org/10.24380/ks45-9147 , Guevara et al., 2020a) and
regional European (CAMS-REG-TEMPOv2.1, https://doi.org/10.24380/1cx4-zy68 , Guevara et al., 2020b) temporal
profiles are distributed from the Emissions of atmospheric Compounds and
Compilation of Ancillary Data (ECCAD) system ( https://eccad.aeris-data.fr/ , last access: February 2021).
