About monitoring here
Prayagraj, still called Allahabad by many, stands where the Ganga and the Yamuna meet, and its storage follows the calendar of the river. The Magh Mela fills the sands each winter and the Kumbh returns every twelve years, bringing temporary kitchens, hospitals and stores on a huge scale. Between the fairs the city is a centre of courts, universities, publishing and competitive-exam coaching, with a medical college hospital and the Naini industrial area across the Yamuna. Phulpur, to the east, has a large fertiliser plant, and Allahabadi guavas are grown around the city. A temperature data logger in Prayagraj might sit in a hospital pharmacy, a publisher's paper store or a cold room. Summers are fiercely hot, with hot winds, and winters are cold and foggy.
Summers bring fierce heat and dry winds, winter mornings are cold and foggy, and the monsoon is humid, while the rivers rise in the rains, so a store can be baked in May and damp in August.
Areas
An industrial area across the Yamuna with engineering and small manufacturing units and older public-sector works, where stock is kept in sheds that heat quickly.
A fertiliser township and farming area to the east, where large stores of bagged product and a township hospital need steady conditions.
The planned centre with the High Court, offices, banks, hotels and many clinics, where records and medicines are stored in older buildings.
Presses, paper stockists and bookshops near the university hold paper and printed stock in rooms that take on damp in the rains.
Guava and other fruit from orchards around the city is graded and sold in wholesale yards, where crates wait in the heat for a buyer.
The riverbank where the Magh Mela and the Kumbh are held, with seasonal medical camps, kitchens and cold stores built for a few weeks at a time.
Industries
A teaching hospital, private hospitals and fair-time medical camps keep vaccine fridges and blood banks that need alarms reaching duty staff through summer power cuts.
Medicine wholesalers supply a wide region of eastern Uttar Pradesh from stores that must hold their limits through the longest hot spell.
Guava growers, sweet makers and fair-time caterers rely on cold rooms and fridges, and a log from each shows how a chamber behaved during the busiest days.
Godowns at the railway junction and on the highways hold goods moving between the capital and the east, and a reading at each bay shows how long a lot stood in the heat.
