synopR 1.0.0 (2026-04-03)
- SynopR is now dependency-free. Only R (>= 4.1.0) is needed.
show_synop_data() and the associated internal functions are completely vectorized, meaning execution times have been dramatically reduced.
- Any SYNOP message is now almost completely decoded by
show_synop_data(). Only groups 29UUU and 9 from section 1 and groups 54 and 9 from section 3 remain ignored.
- Argument "remove_empty_cols" default value from
show_synop_data() have been changed from FALSE to TRUE.
- New function
download_from_ogimet() to retrieve SYNOP messages from Ogimet.
- New function
direct_download_from_ogimet() to download, check and decode all at once.
- New vignette named "Extracted data Reference".
synopR 0.2.2 (2026-03-18)
- CRAN release
- The argument "wmo_identifier" from
show_synop_data() is now optional.
- Column "Sea_level_pressure" from
show_synop_data() has been changed to "MSLP_GH" as geopotential heights for the pressure levels 850, 700 and 500 hPa are now supported
- Tests with ~ 4000 SYNOP messages from Argentina resulted in improvement of internal functions, which now can better handle potential errors
synopR 0.2.0
- Found out some SYNOP downloaded from Ogimet end with "==" instead of "=", now
parse_ogimet() can fix it. Also, show_synop_data() and check_synop() are now aware of this.
- Added new argument to
show_synop_data() named remove_empty_cols which precisely removes empty columns.
- The argument
wmo_identifier from show_synop_data() can be either an integer or a string.
show_synop_data() generates two novel columns: 'Wind_speed_unit' and 'Relative_humidity' (Magnus-Tetens Equation).
- Official WMO Tables for conversion in the form of vectors are available.
- Fixed a bug related with an internal function returning NULL when a string with a "=" character is included in the input, instead of removing it.
- A more clear documentation.
