1) What's New?
I tried to update the PHA code from v52i to v52j but couldn't get it running in time. So, for now, the PHA code used is identical to last year's run but I plan to update this at some point over the year to v52j. The main improvement over v52i is the Rothenberg fixes to the SNHT (Standard Normal Homogenisation Test). This helps to prevent over-sensitivity when there are very few observations. Previously in such low data density scenarios, PHA was susceptible to changes in its allocation of adjustments due to small incremental additions of datapoints. REF/LINK?Due to the retrospective addition of historical data to some stations in addition to the extra 12 months from 2014, there are slight differences in the stations that are removed/kept during PHA/IDPHA processing. This will be documented fully in the Processing Steps section. We have incremented the third element of version control to reflect these differences so that we're now working with HadISDH.2.0.1.
The base QC processing of HadISD is now done using Python rather than IDL. This has resulted in some very small floating point changes that are negligible. (CHECK WITH ROBERT).
2) What's the Same?
The starting station list from ISD is the same - 6103 stations that were initially thought to contain sufficiently long time series. Some of these are merges of 2 or more stations where they have been established to be part of the same station as part of HadISD processing.The underlying QC is the same in terms of methodology. Due to the historical and annual updated this is now HadISD.1.0.3.2014p. (LINK TO HadISD blog post.)
The entire HadISDH methodology is the same:
- equations for converting T and Td to DPD, Tw, e, q and RH are the same;
- methods for calculating monthly means and climate anomalies are the same;
- essentially the PHA methodology is the same (see above);
- IDPHA methodology is the same;
- gridding methodology is the same;
- uncertainty estimation framework is the same.
3) Processing Steps
3.1) Number of HadISD stations:
6103
3.2) Number of stations passing through climatology check:
3679 (2424 failing) based on RH which requires both T and Td to be present. These counts are the same as for 2013.
3.3) Stations removed by PHA:

3.5) Stations Removed Because the Adjustments are TOO Large:
As in 2013 there are some adjustments that are extremely large. On further investigation as part of HadISD many of these are found to be station merges (legacy HadISD code). Such large shifts indicate something pretty screwy has happened to the station. However, its not always clear that the merge is to blame. Given the large inhomogeneity it is justifiable to remove such stations from any further processing as part of the gridded HadISDH. Station moves and most other inhomogeneities will most likely effect temperature and humidity. Therefore a shift would appear in the temperature record but probably not in the dewpoint depression record (because a simultaneous change in T and Td leaves no change in DPD). For this reason any stations with an adjustment applied in T (PHA direct only) that is greater than 5 degC is removed from further processing.71496399999 14.78 MERGED STATION (potential reason) (2013 = 13.99)

3.7 Estimating uncertainty and gridding
The remaining stations are then gridded to create the HadISDH.2.0.1.2014p product which is a 5 by 5 degree gridbox average over all stations within each gridbox (no interpolation or weighting). Uncertainty fields are also gridded in addition to an estimate of uncertainty due to the uneven spatio-temporal sampling across each gridbox. Missed adjustment uncertainty is obtained from a global analysis of the distribution of adjustments for each variable subtracted from a fat-tailed Gaussian fit that infills the missing middle. The PHA/IDPHA adjustments and changepoint frequencies are shown in Figures 1 to 7 below. |
| Figure 1 Specific Humidity adjustment and changepoint statistics. a) Distribution of adjustment sizes. The actual distribution is shown in black. The gaussian best fit is shown in grey. A fat-tailed gaussian merged fit made up of the real and gaussian bins, taking the largest value at each bin, is shown in dashed red. The difference distribution between the fat-tailed gaussian and the real distribution is shown in dotted blue. The mean and standard deviation of the difference distribution are shown. The standard deviation of the difference distribution is taken as the 1 sigma estimate for missed adjustment uncertainty. |

4.0 Differences in gridbox and regional average trends between HadISDH.2.0.0.2013p and 2.0.1.2014p
Version 2.0.1.2014p adds an extra 12 months of data to most stations but additionally, there are some historical additions and amendments due to housekeeping done at the NOAA ISD end. Additionally, even just adding an extra year of data can alter some of the changepoint locations detected and adjustment magnitudes applied. So, we would expect very small differences between version 2.0.0.2013p and 2.0.1.2014p in the 1973-2013 years. To look at this in more detail, Figures 8 to 14 explore differences in gridbox and regional trends between the two versions.
 |
| Figure 8 Specific Humidity gridbox and regional average trend differences between version 2.0.0.2013p and 2.0.1.2014p. a) Ratio of gridbox decadal trends. A ratio greater than 1 means that trends in v2.0.0.2013p are greater than in v2.0.1.2014p and vice versa. b) Scatter plot of gridbox decadal trends between the two version with percentage of gridboxes falling in each quadrant. c) Distribution of gridbox decadal trends. d) to g) Regional average time series and decadal trends (with 5th to 95 percentile confidence ranges in parentheses). Regional averages are calculated by weighting each gridbox by the cosine of its latitude. |

Trend differences are generally very small and discussed in more detail below. The largest differences have occurred in RH, where global trends are now significant, and more negative than before. In most cases it could be argued that changes in the trends are insignificant as they are within both the uncertainty levels of the data themselves and the of the estimated trends.
Trends in RH are more negative in v2.0.1.2014p compared to v2.0.0.2013p. Global average trends are now significant and negative whereas they were not significant in v2.0.0.2013p.
Trends in Td are slightly lower (less positive) for the Globe and Northern Hemisphere in v2.0.1.2014p compared to v2.0.0.2013p.
Trends in Tw are very slightly larger (more positive) for the Tropics in v2.0.1.2014p compared to v2.0.0.2013p
Trends in DPD are very slightly larger for the Northern Hemisphere and Southern Hemisphere in v2.0.1.2014p compared to v2.0.0.2013p. The trends in the Tropics, which are not significant in either version, are very slightly lower and now a 0.00 trend.
Trends in T are very slightly smaller for the Tropics and very slightly larger in the Southern Hemisphere.
5.0 Gridbox decadal trends (1973-2014) for HadISDH.2.0.1.2014p
As demonstrated in section 4, the addition of an extra 12 months of data and in a few cases, some historical amendments, has really made very little difference to large scale trends. Figures 15 to 21 below show the decadal gridbox trends. Gridbox trends are also shown as aggregates by latitude which demonstrates clear latitudinal differences in some cases and spread. The proportion of land gridboxes at each latitude, and the proportion of those gridboxes with data, are also shown for each variable. All variables have near complete coverage in the Northern Hemisphere, with virtually no sampling at the high latitudes and poorest coverage in the Tropics.
 |
| Figure 15 Specific Humidity gridbox decadal trends over the 1973 to 2014 period. Decadal trends are also shown by latitude with the average for each latitude also plotted. Dark grey shading represents the proportion of area that is a land gridbox at that latidue. Light grey shading represents the proportion of those land gridboxes with data present. |
