Absrtact |
There are four main priorities in this issue: (一) patrol and maintenance of existing 250 stations, (二) construction of 5 meteorological monitors, (三) analysis of hot zone data, and (四) public version of environmental information query platform.
(一)patrol and maintenance of existing 250 stations,
1.The comparison results of the first quarter and March did not pass a total of 7 sets, which are 3 sets with missing data and 4 sets with BIAS(%)>50%. Those who have not passed the standard must perform another inspection and comparison or directly replace with new products, including replacement of 2 equipment, and the remaining 5 units have passed the standard after the supplementary inspection and comparison.
2.In the second quarter, there were 2 units that failed to pass the inspection. They were 1 unit with missing comparison data and 1 unit with BIAS(%)>30%. Subsequent testing has been completed..
3.In the third quarter, the inspection operation started on August 19. As of the end of September, a total of 260 units have been implemented. There are 5 units with missing comparison data, and 5 units are due to the atmospheric concentration lower than the standard (≤15μg/ m3) Supplementary test needs to be carried out, which has been carried out in October, and the data is to be analyzed .
4.The overall data upload complete rate of 250 stations averaged 98.6%, the average complete rate of 200 stations in 107 was 98.6%, and the average complete rate of 50 in 2010 was 98.7%, which complies with contract specifications. "The complete rate of valid sensor data is 90%. Above" goal.
(二)construction of 5 meteorological monitors,
1.Five new meteorological monitors were completed in March to assist in identifying the direction of pollution and diffusion through wind direction, wind speed and other data, further strengthening the analysis of pollution hotspots, and improving the efficiency of
