## Met One EBAM

**Simple**
**Portable**
**Comparable to FRM**
**Lightweight**
**Provides hourly**
**	****   ****average data**
**Up to 1 year between**
**	****   ****filter tape changes**
**Small “footprint”**
**Power - AC/DC**
**Meteorology**

## EBAM - General

- Tape sampler
- C14 source
- PMT
- 16.7 LPM
- SSI

## CARB EBAM Configuration

- Firmware R1.50.5
- PM10 Sampling Inlet (BX-802)
- PM2.5 Sharp Cut Cyclone (BX-807)
- Wind Speed/Wind Direction (034A)
- AIRSIS Iridium Satellite

## EBAM Inlet

- PM2.5
- PM10

## Wind Speed/Direction

- WS/WD
- 034A

## Iridium Satellite

- Radio satellite
- AC/DC
- Stronger signal

## Via CARB Internet

**Via CARB Internet**

## ARB E-BAM46/28/2007 12:25:21 PM South Lake Tahoe CA 96150 38.90622N-120.0125W

## EBAM Differences

- No shelter required
- Source & PMT in flow path
- Complete one hour sampling
- Automatic tape advance w/ high loading

## ARB EBAM Program

- Five (5) EBAM Monitors
- Non-Regulatory PM2.5 Monitoring
- Special Projects
- Complaints
- Assist Districts/Counties
- Emergency Response
- District/County
- Public Information – Media
- AirNow

## EBAM Data Validation

- Similar to BAM-1020 data validation
- Download EBAM internal data
- Review EBAM data
- No 915/995 ug/m3 conc. error values
- Average flow (no Qtot)
- Error codes

## Recent Emergency Response

- Angora Tahoe Fire
- Sacramento Trestle Fire
- San Diego Fires

## EBAM Time Series

## EBAM Maintenance

- Bi-weekly flow/leak checks
- Vane/nozzle cleaning
- Inlet cleaning
- Data validation

## Summary

- CARB EBAM primarily utilized:
- When an enclosure is not available
- When AC power is not available
- On short term projects
- During Emergency Responses
- Data review/validation equally important
- Periodic FRM comparisons
