Technical Annual Status Report (Stage 2) for the CLRTAP Inventory Review: Synthesis and Assessment Country report

TIME SERIES

Party: CZ Submission year: 2026

The aim of this test is to identify instances of dips, jumps, and sudden changes in time series data reported by countries. The analysis was limited to data provided in NFR02, NFR09, NFR14 and NFR19 reporting format. Only data reported for at least three years were considered. Years where only NFR02 or NFR09 sectors were available have been converted to NFR14/NFR19. Only the converted sectors are in the time series analysis.

The table below shows data, where outliers in the time series were identified based on the following methodology: Reported time series data were log 10-transformed prior to analysis to reduce intra-series variability and improve general time series linearity. A linear regression was subsequently applied to the log-transformed values for each time series.

An individual value within the time series was identified as a dip/jump if the respective residual value (regression forecast value - reported value) is more than 2 standard deviations from the mean of all residuals in the time series. Only time series where the flagged data value contributed a significant fraction (>3%) of the national total for the given year are included in this dataset for expert review.

Time series where sigma grow largely (i.e. more than 20% of the time series mean value) because of extreme variation in the emission data are also flagged. Zero values indicate small numbers rounded to zero.

The test was performed for the following time series (if data was available):
Main pollutants: 1990 – 2024
HMs and POPs: 1990 - 2024
PMs: 2000 - 2024

If there is a number and a notation key reported, the difference is the number.

Color Key
	Indicates a dip in the time series data
	Indicates a jump in the time series data
	Indicates time series data with large sigma
