THAI WEATHER SITE

Air pollution can be reduced or aggravated by weather. Rain helps in most cases. Dry weather can be a big problem. In monitoring pollution data, checking weather and climate are clearly meaningful.

A climograph shows average temperatures and precipitation by location. There is a 30-year (1961-1990) climograph for Chiang Mai at the following url. On the same site, The Thai Meteorological Department, you'll find similar data for around the country including maps, radar, forecasts and current data as well as historical data.

Some data, like information during the last 24 hours in three-hour increments, is only posted in Thai, but you can dope out the information easily. The date-time group is in the left most column, then --- left to right --- you'll find max and min temperature, percentage humidity, atmospheric pressure, wind direction and speed, visibility (km), precipitation (mm), and cloud cover.

There are a lot of other factors, of course, involved involved in the air pollution problem, some of which we can't do much about, such as atmospheric pressure systems. But we can do a lot more than pray for rain! The enemy is us when it comes to air pollution.

How do I get to the Chiang Mai climograph? Your link leads to a climograph for Bangkok (somewhat out-of-date as you note in your post) and I can't seem to find a corresponding page for Chiang Mai.
