Duplicated lines in bulk data

Alexandre Rio Jul 17, 2017 12:25PM UTC

Hi,

I recently acquired bulk data for several cities and I realized there's duplicated lines.
By duplicated I mean that for the same timestamp (dt and dt_iso) there's 2 different weather_id associated.
Is it a known issue? Should I just ignore one of them?
Is it possible to also have duplicated data (humidity, temp etc)?

Thanks,

Alexandre

This is the file I'm currently using, on the image 7:00, 8:00 and 9:00 are duplicated

On the second image

you can see that the weather descriptions are different between the "same" lines.

Hello,

Thanks for the report.
We will check the causes of this issue.

I think it is not the blocking thing for you?

Hi,

I recently downloaded the Paris Historical Bulk from 2013-01-01 to 2017-05-23, and I realized that several mistakes were present in the database.

For example some rows are missing (for instance, 2013-01-02 13:00:00 +0000 UTC doesn't appear in the dataset), and there are duplicates of some others lines (for instance 2013-10-16 14:00:00 +0000 UTC, but there are many others in the same case). It seems that this is because of weather_main and weather_description (several features for the same date/hour would result in several rows).

Moreover, despite understanding this, we can still observe some inconsistencies between the columns rain_1h, rain_3h and rain_24h.

Is there any patch or solution to solve the problem ? I'm particularly interested in the columns temp, pressure, windspeed, rain, clouds, snow and weather_main.

Thanks,

Selim

Hello Selim,

The resolution that can be offered is that i will provide you a new extract.
I think it can solve the problem of duplicates at least.
Please provide the original bulk file.

Thanks.
