| 27 Sep. 2018 | The total number of unofficial (non-state) weather stations providing RP5 websites with close to real time observational data has increased to 223. There are 128 weather stations in Russia, 55 in Ukraine, 18 in Estonia, 6 in Belarus, 5 in Lithuania, 4 in Latvia, 3 in Poland, 2 in Kazakhstan, 1 in Kyrgyzstan and 1 in Finland. See examples of weather archives at unofficial weather stations located in Vanino, Kanevskaya, Penza, Petropavlovsk-Kamchatsky, Sochi, Kolomyia (Ukraine), Korosten (Ukraine), Hyvinkaa / Mutila (Finland).

| 26 Sep. 2018 | The Met Office of the UK began to provide RP5 websites and applications with forecasts of its new model (PS41). The above mentioned forecast model PS41 officially became the operational model of the Met Office.
The Met Office reported that the improvements expected should be to early winter forecasts (the period of the first snowfall and first snow cover). It is assumed that, in comparison with the previous model, the following weather parameters for the above period will be predicted more accurately:
1) type of precipitation (snow or rain),
2) air temperature,
3) atmospheric pressure,
4) wind.

| 22 August 2018 | RP5 websites provide close to real time observational data, obtained from an unofficial (i.e. non-state) weather station in Simferopol. See Weather Archive and Weather in Simferopol.

| 16 July 2018 | We have released a new version of "Weather rp5 (2018)" application for Android devices.
What's new
1. We have added 94 very beautiful nature photos for widgets. The total number of photos for widgets is 110.
2. Weather data is updated when opening the application from the background mode.
3. At the request of users from India, Romania and other countries, the application language is replaced by default from Russian to English. If the phone is not set to Russian, Ukrainian, Turkish or English, the application is set to English, and not Russian, as before.
You can install the above mentioned version of the app
1) from the website (rp5): page header -> Applications (i) -> *.apk-file
(This is convenient for those users who have been blocked from downloading files from "Google Play")
or
2) from Google Play.

| 22 March 2018 | The language of the rp5 web servers has been updated from PHP 5 to PHP 7. The above mentioned update has improved the performance of rp5 websites: the average download time of web pages has decreased by 1.6 times, the load on the central processor has decreased by 1.7 times.

| 19 March 2018 | Additional work on adjusting forecasts based on METAR data has been completed (see below on March 12, 2018). Now, automatic correction (smoothing) of detectable errors of the air temperature forecast for the next few hours is made as follows:
1) if METAR and SYNOP observations are made at the same distance from the location, METAR observations are taken into account;
2) if METAR and SYNOP observations are made at different distances from the location, the observations of the nearest weather station is taken into account (METAR or SYNOP).
|
| 12 March 2018 | In order to provide users with the current air temperature value as close as possible to the observed values, the rp5 servers have automatically begun to smooth out the detected gross errors in the air temperature forecast for the next few hours. The blunder (that is, a significant deviation of the forecast from the observation) is smoothed out by its uniform linear distribution in the forecasts for the next few hours according to the observations at the SYNOP weather stations for all locations situated at a distance of up to 50 km from the SYNOP weather station. At present, similar work concerning METAR weather stations is in progress.
