These reports include tables of aggregated spending data but not transactional data. However this indicates that the data exists and is in digital format.

The ministry of lands has a database of all land owners and all associated information , but in order to query anything you have file a request on what information you want and also have to pay a certain fee.

The existing official data from Tanzania Meteorological Agency does not include all these items and it is not updated daily.

After doing several background checks , i have not managed to see any official government data which includes all these items.

There is no indication that data set containing all of these items exists anywhere within Tanzanian government agencies or ministries.

it seem data of air Pollutant maybe in the past was Dar es Salaam city in Tanzania http://www.unep.org/transport/pcfv/PDF/DART-OVERVIEWAIRPOLLUTION.pdf

The data does exist, but according to the law , The National electoral council is the sole custodian of this information. So it's is not accessible by the general public and a very few know anything about it, especially after elections.

The Business Registrations and Licencing Agency (BRELA) is the government agency that has started recently to list registered companies in Tanzania. (http://www.brela.go.tz/) Previously there was a company name search feature available on its website, but this appears to have gone, and there is no other form of company data in evidence.
