Consists of monthly printed pages (available as PDFs online) containing station observations. No description of QA is provided on the web site.
Because these data are not in machine-readable format, they
are unlikely to be useful for any systematic study. They are redundant, in the sense that the
same observations should be in the normal

The Harris county rainfall map site allows you to enter an amount of time (in days, hours, or minutes) before the current time, and it produces a map of accumulated rainfall amounts from each site, over the time requested. The data come from 163 automatic remote sensors (part of the flood alert system) across the metropolitan area, and they are “unofficial” (probably means not QC’d). The density of the network allows for detailed information regarding the horizontal distribution of the rainfall. Their locations can be found on a map link and a text link, which includes latitudes and longitudes. There is a link to an archive site where you can indicate a given amount of time before your date of interest to obtain a map of accumulated rainfall, but I could not get this part to work. If this does eventually work, this could be a useful site for modelers, although it looks like the only output would be a map (i.e., no text dump). I suggest a following up on this site to determine if there is a way to order the archived data.

CAMS (TCEQ organized surface met and chem. data)
This website includes information regarding the details of
the TCEQ measurements sites. Many sites
have both meteorology and chemistry measurements. Some have just one or the other. All chemistry sites appear to have ozone
measurements, but some also include NO, NO2, and perhaps other
important constituents. Those with
meteorology tend to have temperature and winds, perhaps precipitation. This site has two links:
1) TCEQ’s Air Monitoring Sites (Regional Map) provides details about the TCEQ's air monitoring sites and air pollution, weather and other parameters measured at each site.
2) Air Monitoring Sites (Table)
Provides a user interface to view sortable list of locations and descriptions of monitoring sites operated by the TCEQ and other entities around the state as well as link to photos of sites, lists of parameters monitored, and current measurements.
This is useful for modelers who want to know the locations of monitoring stations, and what is monitored at each station.
This page provides access to two sources of pollutant and weather data. The
first source, the Texas Commission on Environmental Quality (TCEQ) and local
monitoring networks, provides hourly pollutant and weather data from 1972 to
2004. The second source, the U.S.
Environmental Protection Agency (EPA), provides data summaries and hourly data
collected since 1982 on numerous pollutants and meteorological parameters in

Profiler Network, South
The ESRL (formerly ETL) network page allows access to real-time and archived plots of profiler winds and other profiler data. Real-time plots are provided through a clickable map interface. Archived plots and ASCII data can be downloaded for single profilers. A trajectory tool allows the calculation of forward and backward trajectories using profiler data. The site includes all regular wind profilers from the NOAA and TCEQ network as well as all those installed for the TexAQS-II field program. The data include profiler winds and signal-to-noise ratio, RASS virtual temperature and virtual potential temperature, and surface meteorological observations from profiler sites. Data should remain available for several months after the experiment, as well as the profiler trajectory tool.

This web site allows the user to select a station using a clickable map and generate graphical soundings or ASCII data output from real-time or archived rawinsonde observations. The output format includes all common sounding diagram types and ASCII data formats. Large amounts of data would be difficult to obtain, but this site is the best available on the web for individual archived soundings.
ACARS aircraft observations
ACARS observations are in situ meteorological observations
made by commercial aircraft. The data
include temperature, wind, and often dew point.
The wind precision is not very good, but the temperature and dew point
data are useful for estimating mixing heights and their diurnal variation. Most ACARS observations in
Large network of coastal stations. Some of the reported stations are regular NOAA or other agency stations, and these are not identified as such. The additional stations seem to primarily provide water level, water temperature, and air temperature. Machine-readable historical data are available. Some QA is apparently done, but specifications are not easily found on the web site.
Possibly useful for improving resolution of model validations for simple parameters.

NOAA and DoD Satellite images
The National Oceanic and Atmospheric Administration (NOAA) Comprehensive Large Array-data Stewardship System (CLASS) is NOAA's premier on-line facility for the distribution of NOAA and US Department of Defense (DoD) Polar-orbiting Operational Environmental Satellite (POES) data and derived data products. CLASS is operated by the Information Processing Division (IPD) of the Office of Satellite Data Processing and Distribution (OSDPD), a branch of the National Environmental Satellite, Data and Information Service (NESDIS).
CLASS maintains an active partnership
with NOAA's National Climatic Data Center (NCDC).
NCDC, the permanent US Archive for POES data and
derived data products, supports CLASS through a user-interactive Help Desk
facility and through the provision of POES supporting documentation, including
the NOAA Polar Orbiter Data (POD) User's Guide and the NOAA
CLASS provides data free of charge.
Anyone can search the CLASS catalog and view search results through CLASS's World Wide Web (
CLASS (originally called
Satellite Active Archive), was established as a demonstration prototype for
electronic distribution of POES data in 1994, and became operational in July
1995. During that first month, 379 Advanced Very High Resolution Radiometer (AVHRR)
Level 1b data sets were distributed to 27 customers via the emerging Internet.
During the first five years of operation, the average monthly volume of data
distribution increased to 65,000 data sets with a total size of 1.2 TB, and the
NASA Earth Observatory natural hazards http://earthobservatory.nasa.gov/NaturalHazards/
This is a NASA site that has awesome satellite images due to the following natural phenomena: crops & drought; dust & smoke, fires, floods, severe storms, and volcanoes. The images are organized by event, and are free to all. They just ask for proper acknowledgment. This site is probably of limited value to modelers, but for certain events, such as the Saharan dust events that occurred during TexAQS II, the images may add some visual interest for a case study presentation.

This site has images from MODIS (Terra and Aqua). Images are archived by day, and

The Meteorological Assimilation Data Ingest System (MADIS) is dedicated toward making value-added data available from the National Oceanic and Atmospheric Administration's (NOAA) Earth System Research Laboratory (ESRL) Global Systems Division (GSD) (formerly the Forecast Systems Laboratory (FSL)) for the purpose of improving weather forecasting, by providing support for data assimilation, numerical weather prediction, and other hydro-meteorological applications.
MADIS subscribers have access to an integrated, reliable and easy-to-use
database containing the real-time and archived observational datasets described
below. Also available are real-time gridded surface
analyses that assimilate all of the MADIS surface datasets (including the
highly-dense integrated mesonet data). The grids are

Data Product Description
More than 20 different data products are output from the Reanalysis data assimilation, model run, and model forecast. These products are defined in terms of the NCAR archive names, physical variables, resolutions (temporal and spatial), and media storage size. CDROMS are also used to distribute selected reanalysis products.
